Has anyone sealed/fixed small cracks in their gt taillighs before? I would like to attempt a refinishing job as documented in the How To Section, however one of my lights has a few smallish cracks in them. One is all the way through to the point that there is some cleanup (I think mold?) on the inside of the lens. I am not looking for perfection, but if I am going to use a 40$ can of two stage clear and a day of labor I don't want it to green up again.

Super glue.

I believe that the lenses/covers are some type of polycarbonate. I would imagine that a good solvent glue for acrylic would work. Just make sure that the joint is as clean as possible. I have used Poly-ZAP and Weld-on #3 with good results.

Watch this video from the 3:00 time. Note what he says about accidental spills. DON'T clean them up. If you use the proper glue and syringe, you can fill in the cracks and have a perfect part. I know a little about customizing and repairing these lenses

I would have to disagree with you on this gtoformula. CA, Cyanoacrylate glue would be an extremely poor choice for repairing anything polycarbonate (such as the GT clear lenses) for a couple of reasons. A) The catalyst for these glues is hydroxide ions such as those found in water, or rather moisture. Where polycarbonate is impervious to water, it would likely CA would likely cure correctly. 2) When CA glues do cure they contract, this would likely cause the cracks to get worse, one of the main reason you can't use CA glue on acrylic.

I spent a lot of time on the phone with the folks at BSI trying to find a suitable glue for my trunk seals and I learned a lot about what you should and should not use CA glues on. First on the list were poylcarbonate and acrylics.

Hope you are well, and the NTFC is alive and kicking! BTW, have you had a chance to see Tom Slick's new LS4 Fiero?
