I am concerned about the heat of welding damaging the epoxy bond. The JB Weld package claims that the product, once fully cured, can withstand 550 degrees. To try to avoid damaging the bond, I tried to make the area covered in weld through primer a little larger than the weld itself would require, to create a buffer between the weld and epoxy. The other thing that I'm planning on doing is to do the plug welds one dot at a time. I'm hopeful that by going that slow, I don't heat the surrounding metal to too high a temp. Having a cold garage may help dissipate heat a little quicker, too. All combined, I hope that it holds sufficiently. If I screw it up...I guess I'll have to try a different approach. Can you think of any other techniques that I could try to help avoid compromising the epoxy? Thanks for the heads up!
