Hi everyone,
I have been very busy with customer cars, but I took a little time to do some ceramic coating on my exhaust components.
The coating was sourced from www.techlinecoatings.com . It is the "TurboX" coating, specifically designed for 2000+ degree exhaust gas temperatures (not that I will see that high of an EGT on my car, but it is sufficient for my purposes).
Here's what I did:
1) Disassemble turbo, wastegate, exhaust, dump tube and associated equipment that sees exhaust duty.
2) Prepare parts for bead blasting by taping up surfaces that either need to be completely flat (eg: wastegate mating surfaces), or can possibly catch the individual beads (eg: flex sections).
3) Bead blast individual parts with 120 grit aluminum oxide blasting material.
4) Clean parts with acetone based liquid.
5) Stir and shake up coating. Pour into air spray paint gun, and make short passes until each part is uniformly black.
6) Bake in oven to partially cure, install on car and drive the car to completely cure.
Here are the pics:

I will post better pics after I pre-cure the stuff in the oven.
