ok i used 2 pieces of cardboard and cut 6 inch half circles in each. The cardboard pieces go on the top and bottom of each wheel. The rear was pretty easy not much to tape off.
The front callipers were alittle more time consuming. I got some thinner cardboard that was more bending and got a pair of scissors and cut it out to fit in the places i didnt want to get paint on. I used just regular masking tape. The easiest way to clean is with a power drill and wire brush.
And i didnt use a clearcoat but they do make one for high temperature applications. I didnt think they would need a clearcoat, but i do have 8 coats of paint on each corner.
Very simple process just time consuming to let the paint dry properly.
