A new plywood blade in your circular saw installed backwards. Go slow as it cuts and melts it's way through

Here is a quote from one of the manufactures.

CUTTING
Cut fiberglass, PVC, and Polycarbonate panels using hand or power saws. Saw blade should be fine-toothed carbide tipped, or safety fabric reinforced abrasive disc. Face shields and appropriate safety equipment should be worn.

Thank you both for the information. I've yet to get back to the project, but I'll give it a try, probably with an abrasive disc in my circular saw at first.

Thanks again.

Set up some sawhorses and a sheet of plywood. Set the blade just a hair deeper than the panel. With the panel on the plywood, have a helper help hold it down tight and cut. Dont try to cut an end that is flopping as it will crack. You can cut multiple sheets at a time layered on top one another as long as you keep it held down tight to the ply.
