Admiting fault would be a good step in the right direction. As has been said time and time again, even by Rotarded, there are ALOT of members that despise bad information being tossed around. Most of them no longer post because of things like this.

Outcold - that looks really good. I'd be curious to see how it hold up to the heat especially with the clear. I've been told that clear bronzes when it heats. Did you use a specific high heat clear?

I've always had good luck with VHT products. I consider them to be a baby 3M. If they say it'll work, I'll believe them.

The key is the prep though, as it often is. Brakekleen is a great way to get the grease, grime and dust off the calipers prior to painting or coating. My powdercoating system actually suggests that you bake your part @ 400 for 20 minutes to cook off some of the grease and grime that may have made it's way into the pores of material. I powdercoated an A/C / PS bracket. I spent a great deal of time mechanically and chemically cleaning it till it was clean enough to eat off of. Then I popped it in the over for 20 minutes, being cast AL and all.... the **** that was on it when I took it out was unbelievable. I spent half as much time the second time cleaning it again. The end result was worth it though. Only a few spots actually came though the powder.
Im not too fuzzed yet when it comes too the clear coat as the clear coat is from the same producer with the same procedure too bake, so im kinda counting that these guys have tried their own product and they know it aint gonna bornze off on me.
But as u mentioned the fact that it might, i gained som couriosity if this will actually go down the right way. I also used something similar too clean up the caliper , is it BraKleen or BrakeKleen? didnt cook it off the way u did tho.

Dude. I think he would have figured it out by now. Its not bad for wheels.



50%... hint hint... i wasnt 100%... so i could be 50% right or 50% wrong. I was partially wrong on the temps.... yes. I will admit that. But there is low powdercoating temps such as 295 degrees. There is also high ones such as 425. Which i was also wrong. I didnt know that they could bake at over 400. But i was pretty damn close to the average powedercoating temperature so you have to give me something here.



Can we please, PLEASE just come to an agreement. We are both wrong and right in some things. Apperently i was more wrong. I really want to be done argueing.
Wow, I guess you havnt seen any cracked powdercoated wheels then, because I sure have.

Couple other minor issues, but...My beef was with Rowtarded's post, not your post.

It's really, really hard to argue with an admin/mod. (It also sucks to be one, for many reasons, as you are basically a big effing babysitter....)
You might reconsider that "war" if you knew what I did for a living Regardless I don't feel the need for that. There is an old saying, "numbers don't lie, but what do you want them to say?"

He said 225-whatever, I said 450. Pretty strait forward I think. He said 225-whatever, his best friends father said 395 I think..... Again, pretty strait forward.

It's not that hard to argue with a mod/admin at all. They're people with a job to do. As long as you have a good point and can support it, they'll listen. If you're a child about it, then you're pretty much screwed. I've been banned MANY times and don't have a problem with any of the mods here. I disagree with what they seem to be spending thier time policing but they have thier priorities and thier reasons for those priorities and I'm sure they're legit in thier eyes.

C'mon man, hes 15, he's way more mature and has seen way more than us in those 15 years.

I do know what you do for a living. You work in real numbers, I work in theoretical crap. Although I can beat most laymen, there's no chance of me winning an argument about numbers with you beyond you making major mistakes.

Andd...

I'll be a "******* *******" for a moment, and stop being subtle then.

What Rowtarded posted is chilling. Can you tell me honestly that you are 100% sure about every single thing you've posted on the forums, TTT? A mod saying that you have to be 100% sure about what you post is..... In fact, let me quote him.

If you are going to post about something in a thread, make sure you're 100% correct in your information.
Doesn't that make all speculation threads invalid? All the advice I've posted in the past to try to help people is in violation of this. The majority of the threads I've posted seeking advice violate this. Probably the entire front page of the 2nd gen section is in violation of this.

I really doubt Rowtarded meant what he said when he posted this, but I've read a lot of posts on these forums to try to seek clarification, and I have not been able to get it. However, every alternative meaning of that particular sentence is also chilling - "Only argue with someone if you are 100% correct!". How the hell am I supposed to know if I'm 100% correct? A lot of the time I find out I'm wrong BECAUSE I argue with someone. Or are we not supposed to hold our ground in an argument, and back down immediately if there's a chance we aren't 100% correct?

Like I said, he's a mod/admin-type. He sets the rules and interprets the rules of the forums.

The second part that I find an issue with is "******* *******" being worthy of a warning. I hit the search cap from searching for *******, and when I searched for "******* *******", I also hit the search cap. I only looked through about 100 pages of the latter, but this is the only thread I could find where mod action was taken.

Looking at the rules, it is very obvious as to why action was taken. It is explicitly covered. But looking at other threads, action seems to be applied at best inconsistently.

BTW, as I alluded to earlier, I have been an admin of a forum (Actually, paid to run one at one point...), and it was awful. But this is kind of somewhat important, as at the very least, the first issue *does* affect me. If anyone ever told me they are 100% sure about something, I'd call them an idiot or a liar - as a fellow math guy, TTT, I'm certain you can attest to the improbabilities of that particular number.

I did not realize I would be questioned in my ways. So here it goes:


Don't post technical or non-technical information on ANY type of automotive forum if you are not 100% correct. I figured this was a rule amongst all forums, but I guess after being here close to 7 years now, I might be wrong? Tell me I am wrong about wanting members to post correct information.


The thing that "ticked" me off was that the original part was a member said "xxx this xxx that" and then posts "I am about 50% sure/correct". You don't view this as wrong? I sure as hell do. I don't want people spreading false information on a forum that I help run and put time and effort into to make it better for the entire community.


False information leads to misguided and pissed off members who can't fix their cars. If you want another mods point of view, you can speak with Aaron Cake as I have seen him get frustrated at members posting false information. Also, how do you think products or cars get a bad reputation? By false information being spread around.


If there's any more questioning on this matter, PM me and we will talk, let's keep it out of the this thread.

I can tell you that everything that I have posted that I have stated as fact is 100% correct, yes. The key there, and the key to this thread, is the way in which people post up information. pagon posted his information as fact which we all know now is wrong. Yes there are low temp powders. He should've specified. This instance he was proven worng for many different reasons. One of the most blatant was that whole powdercoating isn't bad for wheels. By posting it like that, he is saying that ALL powdercoating isn't bad for wheels which we know now to be FALSE. I've gotten into a whole bunch of debates where I wasn't 100% sure of something and I ALWAYS made damn sure to specify and make clear the difference between what I THOUGHT, and what I KNOW. Specualtion threads are perfectly valid ways of gaining information and experience, but the posts that are made in them by people who don't know for sure should be made in a way that lets people know it's what they think, not what they know. pagon however, is the worst kind of poster. He doesn't know everything, thinks he does, makes bad posts and then tries to make himself look right by posting up his friends father blah blah blah. We all know powdercoating @ CERTAIN TEMPS is bad for aluminum. He posted up powdercoating isn't bad for wheels at all. What if I used my powder to coat my rims and baked them @ 450*? See the difference? It's subtle, but it's a BIG one and it only takes a few choice words to make a post go from fact to speculation. That's where the danger lies.

Quick example, there was a member here who I discredited a few times and he kept coming back with different screenames to try to get his "rep" back or whatever. He went by Viperkiller, allrotormotor, and a few others that I can't remember. Aaron and Justin know who I am referring to. Regardless.... he decided to take a cordless drill to run his OMP not knowing the condition of the OMP or the speed of the drill or the speed that the motor runs the OMP at. He then posted up, as fact, that the OMP is a low volume low PSI pump. Low PSI as in <2psi. Hailers, we all know him... one of the final 3 that I refer to as guru's that still post, disagreed. He went outside and hooked up a PSI gauge to his omp lines, ran the motor and blew the line off at something like 40PSI iirc. So, what did allrotormotor accomplish except make himself look like an idiot again? See where I'm going here. After reading Allrotormotors post someone could've gone outside and replaces thier busted OMP lines with vacuum tubing thinking that, hey - low PSI. How pissed would he have been when a line failed pissing oil everywhere and drained his sump, potentially catching the car on fire, potentially killing an engine.

There's what you think, what you can sorta back up/50% sure if you want to call it that, and then what you know as fact. If I post something as fact, you can be damn sure of it. If I say something like I think, I feel this way, I'm not certain but here's my experience, you should know to take it differently. Go into the 200mph bonneville thread. Prime examples - I think you should worried about this, if I were you I would look at it this way. I don't have a 200mph car nor do I pretend to. But I can certainly think things and have an OPINION on them, I just don't post my opinion as fact. That's where the big difference is, and that's a huge gripe for me, and some of the mods/admins. That's what makes speculation threads a great way to share knowledge.


As for the launguage, I have no comment

As a math guy yes I can certainly agree that someone who claims everyone of his posts is 100% correct is full of ****, and I'm not saying that all of mine are. I've been proven wrong on a few things that I was unsure of I'm sure. However, what I post as fact is just that. Fact.

I still want to see damaged wheels lol. I hadn't ever heard of this before, and since I'm going into the field of materials engineering it would be an interesting thing to know about. Anyone have any pics or links regarding it?

If you're going into a MAT-E program, you will hit this topic right out of the gate. Trust me, I've been there







Wheels were on a C5 vette. One wheel failure, one beginning to fail.

It is called Powder Coating Inc.
They are out of Mukilteo Wa.
I went to Powder Coating Inc.'s website. It seems like every well put together business. They at least referenced metal fatigue in their FAQ, which means they are concerned about the metallurgical consequences of heat. But do you know what else they said in their FAQ?

You said he's done wheels for Porsche Race teams? Guess what: They are not using cast wheels. Nomenclature is very important when talking about metals! One form of "aluminum" is not the same as another "aluminum!"

It's not the HEAT that is the issue, really, it is the COOLING (as far as a one shot deal like coloring a rim). So you can heat an oven to 400deg? good for you! Can you then bring the part back down to ambient temperature slowly, not just opening the door and wheeling the part out of the oven? skoebl is going to learn about cooling curves in his first semester of MAT-E, just like I did.

The real problem here is that not everyone is going to go to your friends dad. Not every powdercoater understands what happens to the metals as they're heated and cooled. Telling someone "powdercoating your cast wheels is very safe" is like telling someone "open heart surgery is very safe"...in the right hands!

FWIW, Boeing never powdercoats any of their aluminum, regardless of the benefits of the finish.

Alright guys, enough is enough on this issue.

You guys want to continue your battle then do it through the pm process as it already has cluttered the **** out of the OP's thread.

The point has been made here and let's move on or I'll just shut the thread down. :-)

I cleaned up as much of the thread as I could without chopping people's posts to bits and making edits. As much of the misinformation I could remove was deleted. Argumentative posts that didn't include information were deleted.

Please keep all further posts on topic and not about who is right and wrong. This has been well established already.

Further posts that don't directly address facts and just talk about who is right vs. who is wrong will be deleted.
