Red Devil 0816 100% Silicone Sealant
Red Devil is another manufacturer which provides a clear silicone sealant, but they package theirs in a caulking tube, making it more convenient for larger projects than the Permatex silicone sealant. This sealant forms a water tight seal on aluminum, ceramic tile, glass, porcelain, fiberglass, vinyl and plastic. That makes it ideal for many automotive body and interior uses, as well as architectural door frames, windows, skylights, aluminum siding, trim, gutters, pipes and air conditioners. Keep in mind it's not paintable, so be careful where you use it. Cured sealant maintains maximum flexibility and adhesion and will not crack, shrink or peel. It has a 50 year limited manufacturer's warranty.
