I do not have a heater for my garage ( but than again it was 86 degrees here today

) . I feel your frustration with the magnet , I hate it when I work very hard on something and then find I made a simple error and have to do the job over . The worst one that ever happened to me was to replace a transmission and then find out I made a simple error in assembly and had to yank it out again ,ouch .
