Hi all. I'm seeking opinions about success with different Tolex glues. I began with Weldwood contact cement in a can (not the water based stuff), which worked well, but had to be brushed on and caused some stretching. I then started using 3M Super 77, which sprays on. Much faster and less stretching, but after about 6 months starts to let go and gets gummy. I'm thinking about getting a hot glue pot and using hide glue, but don't know much about it. Any tried and tested long term success stories? I sure appreciate any input.
