Good, tough hold

a month ago

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

Q: Will this bond metal to plastic? The latch handle on my colwing is a hard plastic, and it developed a crack allowing it to spin freely on a metal shaft. I am trying to fill the gap and bond it to the metal shaft.

2 Answers

A: Hello! There are specific glues just for plastic that are sold, and called “ plastic weld “. There are various manufacturers of these glues. I believe JB Weld has one also. I would recommend using this type of glue over any of the glue welds for metal. You will have a better chance of being successful using the “ PLASTIC WELD” type glue. Thanks!
