Your concern about once using the J B weld and not getting the handle back off is a good question & concern. I am thinking that even though the stuff is great I would think that one sould still be able to carefuly pry the handle off. I do know that once J B weld has been used heat has no affect on the softening or making it workable. Wores case senerio then the handle needs to be damaged in a way to remove. Replace it now or later if you at some point may need to remove. I good fix for now.
