I hoping you guys could give me some guidance on a project I'm about to start. I need to powder coat some auto wheels. It would be pretty straight forward except I need to powder coat two colors. The center of these wheels needs to be black. The outer rim needs to be a light blue. There is a seam that divides the black from the blue, but the two colors need to run right up to each other and there needs to be sharp line seperating the colors (i.e. the colors do not blend into one another).
Off the top of my head it seems like there are two possible ways to approach this.
First approach - I could power coat the entire wheel in one of the colors (say black) and then tape and mask and come back over the top with the other color. I've never put coats on top of each other and I would be concerned about outgassing from the first coat affecting the finish of the second. Also would be concerned about bleed through.
The second approach would be to mask off the outer part of the rim, hit the center with black powder then oven cure. Once cured I would then mask out the black center then powder the outer rim with light blue and then throw it back in the oven and cure. The only part that concerns me here is that the black center part will be baked twice. Don't know if the second bake in the oven will damage the 1st powder coat.
Would appreciate any advice from someone who has done anything similar.
Thanks,
Scott
