This product was recommended for recaulking/sealing the rubber roof of my RV, as well as we installed 2 MaxxAir ceiling fans, one in an existing hole, plus one in a new hole we cut out

The first time, three years ago, I did a complete sealing job around all vents and skylights, as well as, the seams of the rubber roof
