Yeah im mainly wanting it to look finished instead of the overspray truck color on it now. I figured I'll use a rattle can bedliner for a little more durability instead of just paint.Spraying mine is next on my list. My dad and I sprayed his Raptor wells with a rattle can. Lots of tape and lots of newspaper to block off things to you don't want sprayed and prevent overspray.
I think it may have cut down on the severity of the "ping" when gravel gets thrown up, but it's not going to really cushion. It just makes for a nice clean look and makes cleaning off mud (and cow crap) easy.
