GacoFlex GacoRoof Gray Silicone Roof Coating 1 Gallon - Waterproof Sealant for Flat Roofs, Metal Roofs & RV Roofs - UV Resistant, Weatherproof Protection for Home & Commercial Buildings

Smells like clorox. Yuk.This stuff is great. Used it on cargo trailer roof. Nice & smooth. Got it because roofer used in on my house's widows peak years ago. This stuff really hold up. Is way better than hillbilly roof job by R&R trailer producers. Looked like a 5 yo did it. It was sticking up & overlapping the edge & coming up due to unprofessional application. Their trailers are pretty solid tho.
