I am Sooooo Confused over Paint

Spi
Use there epoxy on bare metal do your body work over it then use their high build primer then whatever base your chose and spi universal clear. There customer service in hands down the best! And you can text Barry and ask for help at pretty much any time. He recommended I get my base from a guy name Chad he sent me some high quality stuff and my job turned out amazing. I have nothing but a harbor freight compressor and a harbor freight paint gun. I sprayed outside also. If I can do it anyone can. Spi is top quality and affordable I highly recommend it! I'll have to dig thru my phone and find you some pics.
