So I guess once you spray that stuff on there it is there for good, right? Of course, that is the point. I've been wanting to do that to my truck, but I'm afraid once I do it I might not like it, but at that point its too late. With paint I can always just paint it again... unless I could hit it with some majic chemical and it melt away leaving beautiful bare metal.
Also, could you post some pictures on how you did some of the tricky spots? I would think it would be tough to get the door handles, door locks, windshield sprayers, cab lights etc back in properly, unless you maybe left them in and just taped them off? Also I would imagine you couldn't hit the cowl with all the holes it has in it, or you'd mostly or completely fill them up and defeat the purpose.
