Instructions for painting:
-Soak the calipers in Evaporust, clean up with a wire wheel. OR have them bead blasted
-Clean with brake cleaner
-Mask of piston bore and passages
-Apply 2 coats of self etching primer
-Apply at least 3 coats of high temp paint
-Optional: follow instructions and bake calipers in an oven.
Instructions for powder coating based on Eastwood's kit:
-Soak the calipers in Evaporust, clean up with a wire wheel. OR have them bead blasted
-Clean with brake cleaner
-Mask of piston bore and passages
-Preheat calipers in oven for 15-20 mins @500F
-Apply powdercoat
-Put calipers back in oven and bake for 20-30 mins after they powdercoat flows.
Alternatively you could hire out the powder coating like you would do zinc coating.
