A good powdercoater won't even put them in the oven with the seals in place. I just sent a whole bunch of stuff for powdercoat, and on every part he asked if there were seals to worry about.
When I do the brembo upgrade they will get torn down, powdercoated, and put back together.

thats the way you powdercoat calipers. if you dont pull them apart and clean them fully before coating you will have brake fluid left in the bores. dot 3 boils at 400*f, (the temp most powders are cured at) lower if it has any moisture in it. the brake fluid vapor then gets all over everything in the oven and can ruin an entire batch and make it very hard to ever get the parts to coat without fish eyes.

Right now I have an intake manifold and supercharger housing and snout out for powdercoat. He is going to run them through a high pressure parts washer then media blast them before they get coated. (He knows not to media blast inside the sc housing, it will be masked off)
If a powdercoater isn't heating up to at least 400 degrees F, its time to find a new guy to go to. I have an intake manifold on my cutty that wasn't done correctly. When it was put back on the car, the foam on the back of a cover left an impression in the powdercoat once the engine was up to temp.
Good powdercoaters that take pride in their work are hard to find. I had the coil pack cover for my lsj done yesterday, he coated it and stripped it twice before HE was satisfied with the finish.

there are low temp cure powders out there for things that you wouldnt want to get to 400*f, however they arent generally as durable. powder also needs to be cooked long enough, a lot of people make the mistake at putting the coated part in and 15-20 minutes later pulling it out. the part needs to heat up to 400*f and remain there 10-15 minutes for most powders to properly cure.
typically if im coating anything that was near oil, especially cast aluminum, after cleaning and blasting i cook it in he oven at 425-450*f to burn off any residual oil thats soaked into the metal, then let it cool back down before coating it. once you coat it and cook it to 400*f the metal wont leach any more oil out into the powder.
