Eternabond is great. I have a brand new camper and on its third trip out, I lost the battle with some low hanging branches. The branches put about 5 small holes in my rubber roof. The biggest hole was 3/4" wide.
I went on Amazon and bought the 50 foot roll of white Eternabond, a rubber roller, and a tube of Dicor sealant.
First I cleaned a 3 foot area around each hole using acetone, a rag, and some elbow grease. Then I put down the Eternabond. Just to be triple secure, I ran a bead of Dicor sealant around the outside edges of the Eternabond patches.
Just be careful, once Eternabond goes down, it won't come back up...ask me how I know lol. Also Eternabond will stick to almost anything, EXCEPT for caulking.
So far it has rained a few times and all looks well.
