The Stovebolt Site Forums The Shop Area Interiors peel and seal on the cab roof

On my 64 cab the outer top skin of my roof was a mess and I have to replace it. Since I have the sheet metal off I would like to put some insulation between the outer and inner cab roof skins. I noticed that the only thing that was there was a small piece of tar paper. Would peel and seal work or would it sweat and build up condensation? I have done a search on peel and seal and I agree that it will work well on the floors etc. I just wonder about the roof with the extreme heat buildup from the sun.

That would work well, however I would be concerned with the Peel-N-Seal getting soft due to the direct heat from the sun and possibly sagging off. To minimize this excess heat, many of the cabs were painted white, from the factory.

The amount of heat generated by the sun is a direct function of the color of the cab. Installing it is a one time deal because you will never be in there again. There is an opportunity for the excess heat build-up to escape because of the opening above the fuel tank in the rear cab section.

Let us know what you decide and how it turns out.

Ozscott, When I had my '66 C10, I cut a piece of lauan(thin wood paneling)then covered it with 1/2" foam rubber and covered that w/headliner material to match my int. cut out to fit the same profile as my roof and gluded and screwed it to my overhead. Worked great cut out the sound and heat also looked great. I also recessed and cut out a bowtie in the foam sorta 3d affect. Good luck

I used a similar "peel and seal" product found at most aluminum fabricators. Was in a 3" roll with a white vinyl outer coating. Used to seal up the seams between insulated aluminum roof panels.

I used it on interior vertical surfaces of the truck, and also the roof. Made sure that I prepped the roof area to get rid of surface rust and cleaned it well with prepsol. The product has been on the roof for 6 months and is still as tight as it was the day I put it on.
