The best (strongest) epoxy is Belzona 1111 also refered to as Belzona
Super Metal.
Super Metal is machineable, no VOC's, no solvents, does not rot, does
not rust, does not shrink, or does not corrode. It is compatable with
all metals.
The same can not be said of Devcon, JB Weld, and most other epoxies on
the market. Yes many claim to be as good as Belzona but experience and
research has proven time and again they do not produce results as good
as the Belzona product. Belzona is may be more expensive but, if
results are important, is actually less expensive.
