Rust.

I painted this Mustang a while back. Jan loves her little car and is keeping it up nicely. I had it back this time to put new rubber in the wing windows. She also noticed some spots,so I looked into them. RUST,it's the cancer of auto body,and here in the Keys it is a constant. We have a very corosive atmosphere. The pic's show the spots after I sanblasted them. Then fiberglass to make the repair waterproof.Painted it will be good as new,till the next time. Rust is a constant.
