Hi Keith. I have a lot of experience with epoxies since I was a kid (dad
was head of QC at a major adhesives firm)......I love the stuff but I am
trying to stay away from a 2-part compound. But the properties of epoxy
is what I am after, consistency and strength, cure time, etc.

To achieve a permanent bond use epoxy resin. I prefer J-B Weld.

You might want to give 3M 5200 adhesive/sealant a look. It comes in
two formulas. Regular and "Fast Cure". The fast cure skins over in an
hour or so and is fully cured in 24 hours. The stuff is incredibly
tenacious and is often misused in the marine world where a permanent
bond is not really what's desired. In your application, the use of
heat, no blow torch required, just a good heat gun, will soften it and
allow disassembly at a later date. There are also chemical de-bonders
that will release the bond. Highly UV resistant. Check-out the specs
and see if it might do the job for you.
Comes in large tubes (9 or perhaps 11 oz.) and small tubes approx. 3
oz. The instructions warn that it must be used within 24 hours of
opening. I've successfully kept it much longer by squeezing out a bit
and then quickly sealing over the opening with tape. It's a moisture
cure product so sealing it well and quickly is the key

Subject: [TowerTalk] Nut & Bolt Sealant
I am looking for a product that I can dispense via a few drops onto
assembles hardware that will dry hard, bond, and resist weathering and UV.
I assumed Locktite Blue or Red would do that for me but I have since
learned there are dozens & dozens versions. I clearly picked the wrong
products as they never "dried" or hardened. I have 263 Red and 242 Blue.
Even a week after application both can be rubbed off flat aluminum
with little effort.......not what I am after.
For lack of a better description is there something out there that has
the consistency of thick nail-polish that will dry hard and help keep
the hardware from coming loose?
