sometimes a panel will look good from the outside, or may be showing slight corrosion, and when you cut it out you find that the inside is corroded, more than you would think. I have seen this quite a bit with any set of panels that comes together and forms a void or area that paint was minimal or not applied at all, these areas are notorious for mice crawling in there and really doing a number from the inside out too. I had a 69 that I did major surgery on for a friend of mine, and the rear main cab support crossmember was completely rotted out from the inside, the outside looked great, but i noticed when I was pulling the cab off the frame there was a a slight amount of rust showing where the cab support bushing was, so I tapped it with a hammer and the whole area collapsed, the more I tapped and scraped it was apperent the entire panel was shot, was the same for the area above the door openings and the cavity above the windshield, a little bump of a rust spot, turned a big hole once I started opening it up.i filled a 2 gallon pail with the insulation and acorns that was in these areas alone.you never know till you open it up though in a lot of cases
