I noticed a rip on the edge of my 5th wheel. I must have scraped a tree and now there is a rip about 3 inches long and about 1/2 inch wide. Is there some goop to put on to seal it back up?
If you are concerned about getting the roof to be stuck back down to the under sheeting, I would consider using something like Lucas #8800 universal bonding adhesive and then apply the seam sealer. This site always recommends eternabond.
