Im a long way from painting the car. But wanted to get an idea of what I was in for. Im useing house of kolor for the car. Primer, paint and clear. I got the KD3001 black primer kit from TCP global. (I'll leve a link). Its a 3 in 1. Sealer, medium build and high build primer. I did the medium on the bottom of my trunk lid. Sprayed nice out of my 20 dollar Harbor Freight gun. The next day it look the same as when I first sprayed it. Coverd good and layed down nice. I had sanded a small spot with 320. Its sands awesome! From what little I did im very happy! I will try the high build next. HoK is pricey. But well worth it.
