I’m looking for either of two products I have forgotten the names to and those of you still in school might still be using. First was a plastic to plastic adhesive we used in junior high school during plastics class. Used to be in a clear bottle with a eye drop dripper applicator. What’s the name or type of adhesive that is clear like water but perminantly bonds acrylic plastic together? The second product is sort of the same thing but more of a lens cleaner to safety goggles. Melts the surface slightly in removing scratches in the plastic. Reason I’m looking for this is for the acrylic plastic lenses on strobe lights which are always getting scratched up. I’m getting tired of replacing them and nothing seems to clean them sufficiently much less remove the scratches. I’m thinking some form of melting the surface will make them clear again. Any ideas on the above products or others beyond super glue which is just slightly still too thick? I would rather not start using a blow torch on them in removing the scratches.
