The blue can be removed. The red requires 600 deg. heat. I once even used green but it is forever, call it chemical welding. It's used for cylinder liners in cast engine blocks etc.

Back in the old days we used a teeny dollop of mom's fingernail polish. It worked. Likely so did the inventor of Lock-tite. lol
