Had these dipped and a body shop was paid a lot of money to rebuild them and get them in primer years ago before being put on a shelf, I decided to strip them to bare metal again because I thought the shape looked a little off and I was needing something to do anyway. As I started with the sander the filler kept getting deeper and deeper then the dents and welded scrap metal came through. Looks like it was in a hail storm then beat with a chain, one was bent in the center of the wheel well and didn't have a smooth spot anywhere on it, the other looked to be beat in and shaped with filler. I messed with the best one all day but think I'm throwing in the towel.
This is what happens when you get something done and then put it away for years, goes along with the body panels I had replaced just to find out years later I spent a lot of money to have new welded over old
