Review: Worked great for a pool jet repair
Review: I like this product for several reasons. It dries to an off-white color that is almost an exact duplicate of the boats gel coat. The product dries relatively quickly, leaving a hard finish that can be sanded. The only real complaint I have is that it’s sag when placed on a vertical surface.
