I need to reattach the mounting brackets to the radiators. I just tried JB Weld and after letting it reach full temp. the left side let go and with a little pressure and full temp. the right let go also. I was hoping for a better result with JB Weld as I have heard other success stories with, not fixing radiators but many other things. I figure it was the heat because it let go within itself, not at the contacting areas. It still has JB at the bracket and on the radiator. I could tig it or I am thinking to rivet it for ease. Lookin for ideas of what has already been done and still is holding. Any high temp JB??
