I am going to paint the firewall using Eastwood paints. Any recomendation on how to get the best result. I am using the spray cans and I have read that it is hard to spray it in nice and even coats without it looking "uneven". I havent actually ordered the paint yet so if you have other recomendations, I am all ears. But Eastwood seems to have the best spray cans in the correct underhood black.
