Cutting Bed Liner - Best Tool?

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?

The bed liner comes from the factory with only the top holes cut out. I used a utility knife also. The easiest way is to cut it from the back side. Also remember, you have to cut the front lip off and the tailgate lip as well if you are installing a tonneau cover. There is a score marked on the underside of both pieces to make it easier to cut. The installation instrucions that came with my bedliner suggest using a utility knife.

Thanks guys! And here I was thinking that someone at the dealership forgot to cut out the holes. Any reason why the bottom four wouldn't be cut out or shouldn't be cut out? I suppose if you haul dirt or sand more than items that you tie down, you'd be better off with the bottom holes left in.
Also, any problem removing the two screws that hold the liner in? Looks like a Torx head to me.

I installed the bedliner myself. The torx screws are self tapping. When I installed mine, I used a cordless srew gun and just the screws. Didn't have to drill pilot holes or anything. They went right through the bed. The instuctions say to be careful and not to overtighten because it can strip easily. You might have to get some type of rust proofing or silicone material to reseal the holes when you take the screws out. The screws come with a rust proof type of coating globbed on the threads for initial instalation. I think when you remove them, you will need more to properly reseal them. Good luck!

Other than the tailgate where does your bedliner screw into the bed? Mine is not screwed into the bed at all...Other than the bed extender like we talked about before.

velvetelvis, the only place the bedliner screws in if you don't have the bed extender is 1 torx screw on each side at the top rear of the bed liner.

If you cut the front lip off of the liner to install the tonneau cover, it doesn't leave any other secured points. I would think the front of the tonneau cover would have a frame secured to the top front of the bed. Maybe that would secure the liner better. I'm not sure. Sorry.

Thanks..

I have a Penda Liner and it is really nice! I think Penda might also manufacture the OEM bedliners as well (Not sure). I left those two screws out since the bed extender holds it down without two extra holes in my bed.

The liner will shift a little when you walk around on it, so I wasn't sure if I left a screw out or something.

Thanks guys. I cut it this weekend and used my sabre saw. Even though I used a very fine blade, the edges were still a little rough. I spent a little extra time smoothing them out with a very sharp Xacto knife. I also installed my new tonneau--an Extang Full Tilt model. Looks good and was easy to install. No drilling and every piece of metal that mounts to the truck has rubber on it to protect the truck's paint. I'll post some pictures of the Extang tonneau soon.
