call me a guy that goes against the grain. ha, I use a jig saw all the time on these lexan windows. I just did my front screen. But, you need to get the finest blade you can, for metal. OR your screwed. That is all. for now.

oh , keep your protective covers on until the end. when cutting, make your cuts as close to the bench as possible, prevents the window from getting too much slack, that can be bad.
