Default Re: 1st attempt: powdercoating aluminum wheels

What finish are the rims now? painted? Chrome? polished?

This is how I do a bare rim assuming its raw aluminum.

1. 120grit Aluminum Oxide
2. Dip in water to clean em or blow em off really good.
3. Wipe down with Denatured Alky.
4. Out gas at 400-450* ( always above cure temps)
5. Let cool down a little (150*-175 range)
6. Shoot the Chrome
7. Bake for 15min or 5min longer after it flows out.
8. Let cool back to the 150ish range
9.Shoot clear
10. Final Full Cure.

The only thing I wouldnt do in your steps above is Turn oven down and crack the door. Just seems like alot of wasted heat and energy to me.

I dont use caswell chrome so maybe Im wrong here and thats the best way to do it with their chromes.
