How can I bond plastic to plastic?

Gluing plastic to plastic usually requires an industrial-strength bond, depending on the type of plastic. Aleene’s The Ultimate Multi-Surface Adhesive has an industrial-strength formula that works great for gluing plastic to plastic. For smaller, more delicate plastics like rhinestones, try using a non-solvent based glue that won’t damage the rhinestone, like Aleene’s Fast Grab Tacky Glue.
