Rubber cement has a solvent that is sold at the big box office
stores. It is a combination of a number of what are called hot
solvents(ones that are aggressive). So read the label first before
buying in the store as most if not all are not good for you. It
comes in quart metal cans, like paint thinner from the old days.
And yes do test first as it is a fast acting and dissipates quickly
on the paper as it was designed for.
