I used this to fix some holes in an aluminum rowboat left by previous owners bolting/riveting various accessories. Filled the holes mainly with small machine screws and nuts, then coated with MarineWeld. 6 years later, it's still holding up and keeping it dry. If the tubes were bigger, I'd coat EVERY rivet on both of my boats in this stuff. It has also come in handy for filling pinholes in small engine gas tanks and even building small accessories for Halloween costumes (like an MIB Neurolyzer!) and
