CARTRIDGE ROLL LIFE
When doing port work, one way to get much more life out of your cartridge rolls is to cut the glue at the end and unroll and cut the sandpaper back to a fresh surface. This will also reduce the diameter for hard to reach places. I found that the higher quality rolls have a better “bond” and they don’t tend to end up like a “flapper wheel”, although that can be handy too. Spending a few more dollars is worth it in the long run. The finer grits tend to work better with this trick. The picture is the same type of roll, before and after a couple peels. Easily three times the life.
