Best Bedding Compound

[atavist]

Just thinking. Last year I was living on a very nice 53 Tayana... well actually lets say she had great potential.... unfortunately the owner was very absentee (ergo me renting her to live on for 50 pounds a week) and had done a lot of work on her himself... one of his disasterous projects was to install deck prisms... unfortunately not only did he cut the holes garishly but he also didn't bed them properly, which of course led to massive leakage and interior damage... some of my mates and I were discussing it and had a rather heated debate about what bedding compound he should have used....

Personally I'm a fan of life-caulk myself and have recently come across T-Rex caulk, which seems to have good potential, extolling itself as a "Fusion Polymer"...

What is your favorite bedding compound?

Ah, that's so dependent upon the application. Having just finished up many projects on our rebuild, we used numerous variety. There's a local supplier here in San Diego--Sunshine Supply with a wonderful sales person who really knows his stuff--Matt. I just give the a call, spec the application (above, below waterline, application temperature, UV tolerance, paintable or not, elastic modulus, color, clear...) and find out what they recommend. They can order anything and carry a wide variety in-house, so "it depends" is the response from me.

For example, for the type of thing you're talking about, we've used a lot of Tremco Dymonic FC for caprails and to re-install glass in our butterfly hatches, too. UV resistant, paintable, fast cure, and inexpensive compared to marine products.

Getting away from high-tech, for solid wood-on-wood bedding (not gluing nor waterproofing) we also use a marine product called Dolphinite

And, in a few places where I'm really concerned about rot (wood-on-wood), I've used a mixture of white lead paste with Dolphinite or white lead paste, beeswax, and Stockholm Tar mixed into a home-made bedding. The thru-hulls on our (wood) transom for the gen-set and engine exhaust were bedded with this mix. The only place I know of to get the white lead paste is George Kirby Paint (508-997-9008). Best pricing on beeswax is on Ebay. We got a 5 gallon container of Stockholm Tar from a friend with a tall ship so don't know where the best prices are for that . The only folks who might use this remedy are folks with wooden hulls (not plywood).
