Hello guys,
I've been reading and re-reading the forum Q&A this winter before I do my first coating job (Near Chrome and Clear Coat on aluminum wheels). Lots of advice here, but I'm a bit unsure on a few details such as heating, cooling, preheating, time between procedures, etc.
Below is what I've put together for the process. Please review my procedure and tell me what you think needs to be adjusted, changed, or added. (bold font is questions I still have):
1.sandblast with aluminum oxide
2.wash with isopropyl alcohol or Brakleen (rinse with water?)
3.bake @ 20-30* hotter than cure temp for 30 min. to outgas & dry; let cool
4.submerse in iron phosphate per instructions; air dry
5.pre-heat wheel again to 250*
6.while still warm, apply Near Chrome powdercoat
7.bake according to instructions on can (bringing slowly up to final cure temp)
8.turn oven down to 150*, crack open door, let cool for 30 min. Turn oven off and leave door open
9.let wheel cool, then wipe down again with alcohol
(OR: skip steps 7-9; bake wheel until powder turns 'glossy', then shoot clearcoat and cure them together?)
10.apply clear coat powder, bake per instructions on can, bringing slowly up to cure temp
11.turn oven down to 150*, crack open door, let cool for 30 min. Turn oven off and leave door open to cool before baking the next wheel.
Any comments about my intended procedure are welcome! I want to do this right the first time.
