I believe JB Weld has powdered metal in the formulation, if that's important to you. Also, OTC epoxies generally cure and increase in hardness over a long period of time, not just overnight.
Hardness and cure also depend on mixing quality and proportions -- hard to achieve good quality mixes with a pre-thickened OTC glue epoxy squeezed in small amounts, measured by eye, out of a couple of tubes, and then stirred with a stick for a minute.
There will be a lot of uncured resin and hardener in the cured coating.
