Art,
Marine -Tex is plenty strong enough even when cured at moderate temps. It will cure overnite at 60-70 deg. I have a co-worker who is a weekend circle track racer(sportsman) He repaired a hole in the engine block of his race car with marine Tex after a rod came loose. He is still using that block after 3 seasons of racing, the Marine -Tex repair is holding up well. I've bedded close to an est 15-18 rifles with Marine Tex, most of em I've popped out after 8hrs cure with never a problem. I'm a weekend warrior on most gun projects so Marine-Tex serves me well.
