I have a sheet of each. What is the preferred method of cutting them?
Rough cut 1/8" to 1/4" oversize with a jig saw, band saw, or table saw with a good sharp blade. Cut to final dimension with a flush trim router bit and a bearing that runs around whatever piece you are replacing as a template stuck on with double sided tape. Hit the edges with a heat gun to make it perfectly smooth (unless you want adhesive on the edge then leave slightly rough).
A fine toothed plywood blade on a skil saw works great. Tape the edge before cutting just in case.

I rough cut with a plywood blade or a jigsaw blade leaving a 1/8" and then finish the cut with a belt sander with 150 grit paper and then hit it with the heat gun for the final finish.

flush trim bit and a template works really well.
The key in all these methods is to have a stable platform. I tried cutting a piece of plexiglass (1/4") with a sabre saw on a picnic table. Shattered is the polite word. Another thought is slow....too much heat and the blade melts rather than cutting. Stable table with a slow feed. Finish with heat or very fine sand paper.
As Ken said SLOW is the key with a hand saber saw or best is a band saw. Also go slow with a router or you'll melt rather than cut the plastic!!
Thanks all!
