content: I am a retired ASE Master rated Auto body guy....That said. I'd steer clear of this product. Poor resultsdue to poor instructions in my opinion.Due to past experience I knew what to do to even get passableresults.1. Clean out pit well!!2. Use a non-oil based solvent like 99% Alcohol to pre-cleanglass area.3. Retain a bit of resin for last step. They tell you in one stepto empty it into fitting, and then at the end ask you to place adrop into the pit prior to placing clear plastic on (my plasticwas amber). Nice trick if you've emptied the resin as directed.My final repair was marginal despite my training.
