Can I beat this with a hammer (rear tire well)?

Thanks. Yea I bet that quarter has some waves in it now. Beating on the inside for a while with a board on the outside.
Yea once I saw how much 3 pound hammer beatings I would have to do to deform the metal in that area on my car, I said eff that.

I would have had to put new quarters on it next! Heck, maybe take it to the frame shop too! just kidding.

I have beat on a few, never distorted any of them, untill going for taller tires.----------bbo
