oh also, saxyman990, you seem to be very knowledgeable about quality coatings, what do you have to say about the Tech Line black satin coating? I've done a few things with it and they seem to be holding up pretty well.

Hmmm.... 1Revvin7 hasn't responded yet. He's logged on a few times since I posted, but he hasn't chimed back in here. I'm actually kind of suprized. I'm interested to hear his rebuttal.

As an FYI, I had a professional coating company do all of my parts, and I'm extremely happy with the results.

There are mixed reviews on the durability of powder on the LIM (some say it fails, and some say it holds up just fine), so I invite you to search through the forums to see what others have experienced. Good luck!

Hmmm, revvin hasn't posted in a while, that makes us doubt his credibility.
Anyway, I sent my exhaust manifold to a local shop to be ceramic coated inside and out. They have done rotary components before and are aware of the extreme heat produced by them. Of course, they did not disclose their exact procedure, but they did say that the manifold had to be prepped extensively then their coating is sprayed on and through the manifold. This method is preferred, they say, to dipping for complete coverage inside and out.
Any comments???

Anyways, where did you sent yours, I will do the same to the manifold, DP, and intake manifold!

I know my 1st post shouldn't be in this one but I lurk here from time to time because I'm prob picking up a 87 FC. Ive been searching about the coolant seals going bad and ran across this post somehow.
It sparked my interest because I own CE COATINGS and Do Ceramic,Thermal and Powder Coatings. Along with being a Aviation Tech. I'm not here to sell my product etc. Matter of fact Who knows if I'll post anymore until I do pick up that 87 my buddy wants to sell.
I just wanted to totally agree with EVERYTHING saxyman990 had to say. I loved your "NICE WAY" of calling BS 1st.
Also anyone who wants to do the DIY coating PREP is your #1 priority. Some need baked,some don't. OUT GAS EVERYTHING that does need baked.
Tech Line makes great products thats who I use. Some you need to be a business to buy some you done. If anyone needs help,tips ,tricks,info etc feel free to e-mail me. I don't hide anything to say well I cant give you all my secrets like some companies do. There are TONS of people out there who can do coatings so why hide any info.
anyways I can't wait to get my hands on this rx7 here local and rebuild the thing. AWESOME SITE btw..

Pretty good first post Noob.
There is a guy on here trying to do powdercoating for people that doesn't even know what degassing or outgassing is. I tried nicely explaining the procedure to him but instead of learning, he continued to pump out junk, half-coated parts. In the end sometimes you just have to be blunt with people for them to get the hint.
There are some people that really know their **** on these boards though, no matter what aspect of automotbile tech happens to be being discussed, so BS is eventually flagged. Great for consumers, bad for dishonest sellers!
I think the supplier of this misrepresented coating could still aquire business if he came back with the correct data (the factual figures look plenty good) and an apology.

I totally agree with everything you just said. I still learn new stuff all the time and Ive been coating for 6 years. Always find better products and different ways to do stuff....
I hate seeing JUNK work out there. because it make noobs to the field of coatings think its all junk.

DId you send it out to QC Coatings? I was planning on dropping off my manifold there sometime within the next week.

Who mentioned coating the inside of the rotor housings? Maybe my memory is failing me in my old age but I seem to recall the "chrome" surface having micro pores/channels for oil to assist in lubrication of the seals. Maybe Saxy knows this but can you think of any application that uses a coating like these (the ceramic coatings being discussed) on a frictional surface? Maybe you can machine this stuff smooth enough for other internal parts not needing the lubrication.

What is "outgassing"?
It seems that everyone agrees that 99% of a quality coating is prep.
Could someone explain what the proper "prep" would be for using a baked coating?

There has been talk before about getting seals coated to help with friction as well as wear. I just wasn't brave enough to try it with my rebuild. Maybe if this rebuild doesn't work I'll give it a shot.

Unfortunately, ceramic and powder coatings usually require a baking period in order to cure. If the part outgasses during the curing phase, it can cause pinhole flaws in the part. This is bad for aesthetics and for durability. So coating suppliers to go to great lengths to ensure outgassing doesn't happen during the coating process. There are several ways to do this.
Typically, the main way to prevent ougassing during curing is baking the part prior to doing any of the coating (usually done at 5-600degrees). This will cause the part to get rid of all it's trapped gasses prior to the coating. There are also other methods of curing the coating that will help to eliminate outgassing. Some companies use infrared or ultraviolet curing rather than the traditional convection.
Proper "prep" of the part includes outgassing any trapped air prior to coating (done by the methods I mentioned above), Cleaning the part thoroughly (typically done by thermal or chemical degreasing), and then usually some type of media blasting or sanding to ensure the part is clean/smooth and ready for the powder or ceramic to be applied. At this point the part can be sprayed/coated, and then baked until the coating has cured. Different coating companies will prep the part in different ways, but these are the typical methods used.
