My truck came with the Chevy bed liner installed. (My dealer installs them on all the trucks it sells.) Well the person who installed it only cut out the plastic for the top four tiedowns, not the bottom four. I'm going to remove the bed liner this weekend (only held in with two Torx screws) and cut out the bottom four myself so all eight tie downs are available if I need them. I want to do this before I install my tonneau cover, so I don't have to remove the cover hardware later. What is the best tool/saw to use for cutting the bedliner? I'm thinking of drilling a hole in the center of each cutout, then using my sabre saw with a fine blade to remove the rest of the plastic cut out. Do you think this will work OK, or is there something special that's needed to cut the bedliner material? Anybody cut or trimmed a bedliner before?
