Will nail polish remover thin rubber cement?

Yes, nail polish remover can thin rubber cement because it typically contains acetone, which is a solvent that can dissolve certain adhesives. However, this can alter the properties of the rubber cement, potentially making it less effective. It's advisable to test a small amount first to see how it affects the specific brand of rubber cement you are using. Always use solvents in a well-ventilated area and follow safety guidelines.
