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?
