Default Tips for proper application of DIY CASWELL black satin coating onto headers?

Looking for best practices to apply DIY black ceramic onto brand new EL tubular headers. I have the coating, compressor, spray gun, sand blasting media.

So far this is what the manufacturer recommends:

APPLICATION: Sandblast all parts with 120 grit aluminum oxide. DO NOT USE GLASSBEAD. Clean metal using conventional cleaning methods, with acetone, lacquer thinner or other similar non-petroleum based solvent.When the surface is clean and dry, apply a thin even layer of coating using an airbrush, detail touch-up gun or other spray equipment that allows for application of a thin film of approximately .001" to .0015". Avoid excessive build-up of material as this can lead to loss of adhesion. DO NOT APPLY A SECOND COAT AFTER THE COATING DRIES. The coating will air dry to the touch in a few minutes. Install on vehicle, as the coating will cure with exaust heat.

CAUTION: Excessive exhaust heat due to a poorly tuned engine can damage the coating during the cure period. Do not install on a new engine untill all adjustments have been made to the valves, timing and jetting. Allow the engine to idle, or drive gently for approximately 30 minutes or until no vapor/smoke is given off by the coating. MAINTAIN adequate ventilation during this process.
Full cure occurs at 750F Especially effective on Turbo housings, head pipe and down tube

Questions so far:
  • How on earth to control the film thickness?
  • Can sandblasting remove protective chromium oxide film on SS304, should I just lightly rough surface with sand paper instead?
    Any airbrush kit recommendations?

i have did the turbo x coatings . you have to use 120 or heavy aluminum oxide grit .
used 80 from habor freight. sand blasted the living daylights out of it an heated up with a map torch, then it cooled off wiped it down with actone. a few times.
used a detail gun then coated it with the turbo x coating making sure not to over spray meaning not drippings . this is a one shot deal can not recoat if dried it will peel off.
.
304 just sand blast it .
detail gun from habor frieght
