I used dupli-color truck bed coating on my 51 frame, firewall, radiator support, ect... and it works and looks great, its very forgiving on rough metal & covers alot of imperfections and its paintable, I used this stuff on my 86 C20 and other projects and it holds up good. but I think I will use undercoating on the backside of my fenders, under the cab, for protection from rocks being thrown up by the tires "I hope"
Just a thought

Some people are like Slinkies, Their not really good for nothing... But they still bring a smile to your face when you push them down the stairs.
