Once in a fit of frustration, I brushed rubber cement on the back of a ruler and let it dry. In my experience, it works the best of all that was mentioned. It does get "linty" and doesn't work as well after a LOT of usage BUT it comes right off when you rub it with your finger and you can put some more on. And just a weird thing....it costs less at my WalMart if you buy it in Home Improvement than if you buy it in Crafts. Same bottle, same size and everything....but about 50 cents cheaper in HI dept.
