The banana skins are pretty maleable, not 2024, so you can hammer them out easily. I got tired of the PO's dents a few I put in myself, so I thought I'd take a shot at "fixing" them.

I'm no body worker, so I lack the panel hammer with the curved face and the sandbags that would allow me to get a smoother finish, but I don't think you're going to get all the small rock dings out anyway, so a few hammer marks are acceptable to me, compared to the big dents. I just cut a couple pieces of 2X4 to approximate the final curve and took the big dents out with those, then used the plastic and ballpeen hammers against the steel table saw top to get the smaller dings. You have to be careful as you do this and
stop early, or it gets worse with hammer dings, not better.

The finished product isn't perfect. I'll post a photo of the installed skin once it gets buffed a little to see if it's really an acceptable repair (tune in next week).
