[DeTomaso] Powdercoating Campi rims

I have had 10 Pantera wheels powder coated and none have failed so far.
I use nitrogen in my tires and the tire pressure does not vary.
The finish is more durable than paint, but there is a possibility that you
can can get out-gassing at any stage and that will cause a bubble.
The finish is also not dead smooth but a slight orange-peel, you can paint
over powder coat, it is a great key, if you wish.
It will help prevent corrosion that mag wheels suffer from especially in
the hidden areas of the wheel.

temp
of 1107 and the melting point is 2002 degrees F.The temps for powdercoating
is 400 for 10-15 minutes, no where near the critical temps to hurt the

any

powdercoating. But this is just my opinion as a professional powdercoater."

Posted in 2009 and no one came back to him with a failure.
