Ok I'm powder coating Stupid
How do you basically do it?
Is it just spray on and bake?
I thought you had to some how connect the parts to electricity for the powder to stick to it?
What about bare metal parts? I can't imagine you being able to spray the coating on something that has that thin protective layer of oil to prevent it from rusting, so did you have to sandblast anything and then immediately coat it?

powder goes on electrostatically, it's a low pressure (15psi-10psi) system, it's like shaking baby powder on a part and then you bake
prep/application is the key to a good finish, my secrets are acetone, more acetone, and some more acetone
it's not my motor, it's r71's motor, rob golden at pineapple still has my motor, ARG

At how many degrees and for how long?
Oh, is it possible to powercoat an allready powdercoated item, or must it be stripped to bare metal?

400F, you can use your kitchen oven if you want
it'd be best to strip the item, stripping powder is not easy at all
let a professional strip it, and you can powder it yourself if you buy the gun

On the front plate, the chroming makes it look like that or did you use like a pearl in it ? That looks sweet, if I knew you could powder chrome I wouldnt have spent so many hours polishing all my stuff...!

that's just straight up powder man, no special tricks other than good surface prep
here's the tranny bellhousing which i spent less time prepping, and thus, some embedded chemicals in the metals released gasses making little pits

and on the last pic, i went and cleaned off the excess powder that ended up on the mating surfaces (tranny/engine)
looks a lot better, i'll take pics of the whole tranny reassembled when i'm done

I also saw the reflective chrome and both are different part numbers.
Have you seen both?
Did you do the inside of the bell housing in a different color than the outside? If so did you have to do it twice?( bakeing process, or did you spray both then bake?) Looks nice, and I bet it is easier to clean. And it's protected from the elements now.( Our Aluminum out here gets ugly fast! I may do this now. Thanks for shareing. Dave

i did the outside chrome and then clear, i was worried because the clear yellows above 350F when you're curing it, but you "run it out (melt it)" at the standard 450F
i did the wrinkle black on the inside last, and surprisingly it worked, i think the trick was that i turned the inside facing down, so the heat got trapped in the bellhousing and baked it faster
eitherway, if i did it again, i'd do the black on the inside first, and the chrome last
i had a tranny leak before and it pissed me off when i wiped off the fluid, because it had stained the bellhousing, so i couldn't tell where the leak was coming from
also i figure it will make it easier to clean out since i've pulled my motor so frequently, makes handling it a lot better

i use a kitchen oven and a hotcoat gun from eastwood, a 50lb abrasive blaster and acetone for cleaning
the secret to good setup is to prep well, blast throughly, and to mask well
having the plugs/tape/masking accessories helps to keep the part functional, determining the bake times, etc for a part is crucial as well. it helps to have someone with experience guide you and help prevent mess ups. baking is a good method but infrared lamps work well too, just take longer

Ihad my upper plenum powder coated wrinkle black with jet hot in the center and underneath.
looks sick.
I am going to ceramic coat the outside engine block with near chrome.
i just want that bling bling look, even on the iron block.

Jet hot ceramic coating near chrome has more of a metallic look than powder coat.
BTW, I think that near the exhaust ports and turbos is where the heat might start to degrade the powder coat over time.
