you are my hero. may your mustang live long and prosper

 

The other pictures of the rust was after paint was removed. Here's a picture when it still had paint on it. Before I started any removal. A real bad patch of rust over the passenger window. But only surface rust.
Used airplane stripper for the paint. Then a wire brush, synthetic steel wool and the Phosphoric acid. This one didn't leave any pitting and is completely gone, but it did take some elbow grease. I do have a few that were hidden by paint, the rust is gone but there is pitting on the surface. (visible in the the other pictures)
for the paint...I started by sanding, but I don't like the sanding marks in the metal and it leaves low areas of paint. I *HATE* the stripper and the mess and it does burn if you get it on you,but it leaves the car with clean metal and no sanding dust flying around.

 

phospheric acid is the great stuff...you should try it..
