Your Favorite Adhesives

[thinwater]

Epoxies (including thickened) and polyesters are obvious. Also 3M 5200 and CT-1. 5-minute epoxies are good for tacking things in place. Thread lockers. But what else?

• Plexus. Many newer boats are practically built with the stuff, including keel grids and bulkheads. Also attaching threaded studs and gear to walls (such as electrical panels). I'm guessing MA 310 is the most common formula, but they make a bunch.
• Other methacrylates. Devcon Plastic Welder seems VERY similar to MA310, and they are both ITW brands. I've used it for a few household things, but never researched it. It seemed very good. I need to learn more about this.
• Sail-specific adhesives. I did some testing and was not thrilled with the long-term UV results of most.
• G-Flex. Really, in a different catagory from other epoxies. MUCH better with plastics, including PE, if properly prepared. Competing products?
• Waterproof epoxies. Everyone should carry some for emergencies. It works. Splashzone and JB weld version are good.
• Spray adhesives. Like 3M Super 77. Good for fabric hull liners.
• PVC glue.
• Inflatable repair glues.
• Glues used on furniture. Wood glues, including waterproof types. Big topic.
• Whatever the "glue" was that they ran out of in "A Christmas Story."
