Body saw or jigsaw here. Then we sand the edges and roll them as well.

Jigsaw works for me. Not to fast or it will melt. Make sure the bottom shoe of the saw has no burrs or it will cut through the protective paper. I apply tape to the bottom of the saw/ If you want to finish the edges pull the protective film back about a 1/8" so you can sand it with out getting the film in the sand paper, use 150 grit to finish. Doug This vent is Lexan
that looks great. Any blade work best?

Jigsaw.... sand the edge so its nice then warm with a propane torch to re-clear the edge... just go lightly with the torch... try it on a piece of scrap first to get the feel

Jigsaw and sand. I used a blade made to cut plastic. Make sure you use scratch resistant Lexan and not GP general purpose.

Would the Arizona sun do the same thing?
Maybe if its thin enough... I use to watch the guys in the plastic shop at work form it but I forget the temp they would heat it to.. it varied on the thickness

Lexan does not like heat. Lexan has a high moisture content which will form air bubbles when heated. When Lexan IS formed with heat it is slowly (hours !!) brought up to temperature to remove the moisture. Its then formed and allowed to cool.
Plexi is easily formed with heat, but that's not what you're using!
If you need to bend the lexan, it can be "cold" bent in a brake. Thinner material will easily go 180* and I've bent 1/2" material past 90*.
If by "forming" you mean curving it to fit a window opening, I'd suggest you just put it in place and fasten it down to take the curvature. Hopefully your material isn't too thick. A customer of mine has a chump car and they use 1/8" material.

It did take them hours to heat it up.. then they would place it and let it cool overnight.... I use 1/8" for the windshield and rear hatch glass... that does form easy without any heat

All I'm making is about 5" pf rear spoiler and "vent" windows. They don't have to be perfect If I have time I might make some sail panels as the trans am looks kinda silly w/o the rear hatch. Not much curves to make. I bought a sheet of 3/16 or maybe 1/4....
I made plastic bumpers for my Valiant and they turned out very nice.. I vacuformed them... I mounted the bumper up on a piece of 2x10 on posts.. heated the plastic with a heat gun and propane torch.. when it sagged down I tape the edges to the wood then I slowly started heating and then turned on the vac pump.. the vac was applied via the back of the board through a hole that the hose was in and taped off... a couple hours later it was done and cooled it over night and trimmed it
