I painted my firewall with eastwood underhood black, after allot of prep gave it a coat, then gave another mild sanding and a second coat. I can't seem to get an even finish coat. I had a friend who has more experience painting made sure things were correct and gave it a third try better but not right? Has anyone had much luck with this product, try to figure out if it's me or the paint before I move onto test rest of my underhood painting. Also I am not using a rattle can, thanks.
