I finally got back to this task. I wound up going a different way, sort of. I was hoping for a good solvent fusion bond and assume the lenses are acrylic, or maybe polycarbonate. Either way, the proper weld solvent would be methylene chloride. Turns out that aircraft paint stripper is basically a gel form of methylene chloride. That might be what the 3M adhesive is too. But I had a can of stripper on the shelf and an old and busted up tail light lens to test on. It worked great. Nice, strong, solvent weld. I have my good lens clamped and curing now... and the price was right.
Clean very carefully with a loctite primer then use loctite plastic gell superglue,not the $2 shite,considering the value of the lense don't cheap it ok,you will be good.
