This has been bugging me for a bit now. I am wanting to powder coat some spar brake calipers that I have for my car but I am not sure if I can use any color powder coating or if I can only use the high temp stuff. These are for a sports car and I am planning to auto-cross the car so they will see some above average use. I just dont want to do a good job of coating these things only to have the stuff fall off from getting too hot. Also, is there any special steps I need to take to clean them?

My regular steps are to:
1. Soak parts in mineral spirits for 1-7 days to remove any grease, oil dirt, caked on stuff, etc.

2. Let parts dry for 1 week to make sure all the mineral spirits have dried out of the part. I also spend this week removing any flashing or unwanted/not-needed bits from the parts. Some parts are for more then one car and have extra parts not needed for my car.

3. Final prep. media blast, clean with acetone, let dry and PC.

any advice would be great.

Also, I've got some parts with vacuum diaphrams in them and not sure they can go to full temp. I know they get up to an easy 200° F but not sure the exact number. I just dont want to push my luck since some of these parts are hard to find and or not cheap to replace. things like the EGR Valve, vacuum advance on my distributor. Stuff like that. any ideas?
