1stproject, I had the entire body, fenders, doors, hood, frame of my 49 sub sandblasted locally at a very reasonable price. No warpage. If you go this route you need to find someone who has experience in doing this. I found after trying the stripper, DA sander and elbow grease method that it was taking forever. IMHO blasting is the way to go and it does a much better job. It worked for me. Weeds
