I use the duplicolor chrome spray paint it works really good. What I learned if the part you are painting is nice and smooth. It will have a higher shine to it. So what I do I prep all my parts the best I can then I spray clear coat straight on the parts. If the clear is nice and shiny and smooth that what you want. I let it set up for 2-3 days then clean with wax and grease remover. Then spray the chrome paint. You will see a difference in shine. Hope this helps. ALOHA
