I had to re-glue the carpet on the inside wall of my aluminum boat, a Sea Nymph GLS 220. This Roberts carpet glue seems to be working great and is non-toxic/non-flammable, which is important on a watercraft. I like it because even with exposure to sun and water, this glue delivers a strong bond on various carpet backing types, including polypropylene, rubber, and urethane, among others.
