No bother at all. The parts were bead blasted in my garage in a blasting cabinet that I picked up from Harbor Freight. Then cleaned with wax and grease remover. The paint is a high temperature (500F) ceramic engine paint by Duplicolor (aluminum). I was going to have them powder coated but decided against it for cost reasons. I am not sure how durable this paint is but it seems tough if you let it cure the recommended full 7 days before being rough with it. It can be handled after one hour but it is still soft at that point.

Hope it helps some
