Today I dropped the last third of my bellypan as there was a large rot hole in the trunk area. Also I could see rust.This is what I found. The frame will have to be replaced for several feet and several outriggers replaced along with cross members
There was foam insulation under the Caravel
stuck to the plywood floor. Was this done by the factory? When it gets wet it stays wet! which causes rot. I had a '50's FeatherCraft Clipper where this was done as flotation and it held water and caused the aluminum to corrode. I scraped it off the back end of the trailer. I think the rest of it should go. This would require the dropping of the entire bellypan. Has any one out there had this type of insulation and did you remove it? I was expecting fiberglass. I will see if I can figure out how to post photos of the foam and frame rot.
The Restoration Begins!
