Has anyone successfully used Flex Seal paste to make replacements for worn rubber parts?
Yesterday I rebuilt an air-powered 1/2" x 12" belt sander whose rubber rollers had disintegrated. The larger drive roller is now a short piece of heater hose on a lathe-turned spindle, crowned with a file, and the smaller knurled brass end roller was reshod with friction tape which is probably not a durable solution but is easily redone.
I used Flex Tape to build up the sole of a comfortable old boot and it held up very well, better than the original dense foam sole, and wasn't any more slippery on ice.
