an old hot rodder who lives down the road from me dropped in while i was working on my car to check it out. he was wondering what he could hear "rumbling" from down the street. anyway, when he saw the primer on my car, he had a tip for me. he said i could sand the car with extremely fine sandpaper and then wipe the car down with pledge furniture polish!! he said it seals it in and the water runs right off it after. i'm not sure that i'm brave enough to attempt this, i just thought it was interesting. anyone else ever hear this?
