Hi All,
I'm a little confused on what is the recommended process for sealing the corners. When I did my trailer 6-7 years ago, I put butyl putty tape between the skin and roof lap, then again between the j-rail and roof lap. When the trailer was originally built, they didn't do anything in between the roof and skin, as all I found in there was dirt.
In doing research, I couldn't find definite opinions on whether to install putty between the roof seam and skin. Some people talk of putty, then a caulk bead to seal the putty form drying out.
On the Shasta Airflyte and most canned hams, that seam runs along the roof line, then becomes vertical down the front and back and then past vertical as it get's closer to the bottom. Without something in the joint, isn't it inviting moisture?
I'm redoing the seams in the back of the trailer. I had a leak on the curb side, that I think was actually coming from the Shasta wing attachment screws. Unfortunately I just redid the back last year to deal with termite damage, which I think we perpetuated by a leak at the rear window. This new damage is even higher up than the last repair, and involves stripping the rear even higher than I have ever gone before before, if only by about a foot. So when I put this back together, should I put the butyl tape back in the bent over lap between the rear skin and side skin? Or a small bead of Tremco 635?
