The inner panels and ducting were covered in fifty year old under seal. "Old guy Scott" took these parts to the local welding supply store. They dripped liquid Nitrogen on the under seal, you could hear it cracking  and popping off. Photos 163 and 164 show the great job they did. Next came minor sandblasting, sanding and metal prep. Some parts received zinc coating before the final paint. The paint is Dupont Centari, the same as the body will receive. "Old Guy Scott" says it would be nice to dip the parts, but with no such facilities nearby, this system works fine.
