I disagree.
So do all major industrial manufacturers of specialist epoxies.
Hysol (locktite) 3478 is one example.

Rated strength in crush is 1000 kg / cm2.
So my 2200 mm long rails, 2 of, 35 mm wide, have a 3.5 x 220 x 2 x 1000 = 770.000 kg crush rating. Each.
== 1.5 Million kg.

Very much like using loctite on screws. A machined flat surface to the manufactures specs is always the best way to go.
