I just bought a 63 Impala SS that was pretty much sanded down to bare metal and left for 3-4 years so it's covered with surface rust. What's the best route to take to get it back to good bare metal? I was planning on using a DA sander with 80 grit and just sanding it to death. I heard that sandblasting will warp the metal and I called a media blast shop and they told me media blasting won't remove rust. Anybody been through this before?
