Mine always had correct coolant and changed every 3 years.
The radiator still died with plastic imbrittlement. For epoxies, there is a operational temp range. Pulled a MG head one and the valve seat was being held in with JB weld. Well, I would have stake it and at least re-ground the offending valve. The prior owner relied on what appeared to be JB weld.
Fix was easy.
Boating story: Many ppl car epoxy repair kits. West was a big brand. Others opted for 4? or maybe it was 5minute epoxy which is WAY less expensive. The repairs came loose and reading the epoxy packaging- it wasn't completely water resistant!!
Metal fortified JB weld has probably the same epoxy matrix w/metal. Hence, it will have the same water/chemical resistance. The metal will give it a higher psi compression strength. Shear properties are a function of the epoxy, not the reinforcement.
