Here's my sample metal plate after clear coat. These are not the colors I am using for my wheels, just what my fabricators had on hand. The regular pinstrip paint was a bright orange and heat resist was dark. When it came out of the oven, we couldn't tell which was which! The base metal plate is done in "black chrome" powerder coat, which is a translucent black shot over sand blasted aluminum. You can see aluminum through it, making it a charcoal color with a metal flake appearance. It looks cool, but not what I wanted.
you can't feel the pinstripe paint through the clear coat and this technique allows you to do very fine striping that is incredibly durable, without leaving a "buildup" edge that you get when you mask off an area then shoot two layers of powder coat.
I'm having
Ron Beam do the striping.
