That might well be the best option then, for those with access to Suncorite. For those without, look for a substitute or powder coat... Powder coating needs 350-400 degrees F to cure, so presumably JB Weld won't stand up to that, or just won't provide an impervious enough surface that the powder coat finish is the same as on metal surfaces(?)

I have no information on cerakote etc., but that might be another option with the Lab-Metal or JBW.
