Replace cracked lap seal, or tape it?
Hello, I picked up a 2000 22í Kustom Koach class C and now have some work to do. Vents on the roof were sealed with thick lap sealant, I believe, that is cracking badly, and is so thick that it traps water up there. Should I scrape it all out and replace it, or go with an eternabond type tape? I believe that the roofing material is a layer of rubber - pretty faded pinkish stuff. Seems to be holding up, but I really want to get all the cracked sealant gone.
Thereís probably a great thread here covering this but I havenít come across it.
