Is JB Weld electrically conductive?
I can not speak for JB WELD but I do know, for a fact, that BELZONA (1111) Super Metal is not conductive. It also will not rot, shrink, rust, or corrode. No solvents in Super Metal and does not stink like JB Weld. Excellent compressive and shear-adheision strength. It will stand up avgas, mogas, or jet fuel. It does not run off like JB WELD. I have built Belzona 1″thick on horizontal and verticle surfaces and it stays put. Amazing stuff, to say the least!
