I had a '69 that was a burn victim. It had sat out after being burned. The best advice is to neutralize the acids that form as a result of the fire. They pretty much ate the interior metal. The roof was a total loss (warped/rusted) and the bondo in the car had lost adhesion (you'd probably remove it all anyway). It was rebuilt into a tube chassis race car (probably the best use for a burned body, but it can be made nice, i's just expensive!). In the case of the one I had it'd sat out 15 years, it'd been better the sooner it was gotten to (to stop the massive corrosion!) don't overlook nooks and crannies!
