So I bought a couple of Lexan windows last week - it is 5mm thick MSA-spec proper Lexan to go in the rear quarters of the circuit Bug. I am wanting to cut them to install some NACA ducts in each one. Can anyone offer any tips for the best way to do this - is a Jigsaw OK? Obviously making sure I don't scratch it is the easy part (tape on the jigsaw foot, etc). My main issue is getting a good edge - I was thinking of a medium or fine wood blade, starting from drilled holes at each corner, and then finishing up by hand. I read that if I am not careful the Lexan can melt as I cut - is that right? I also read that after hand sanding I can finish up the edges with a gentle flame to turn the edges glass smooth - is this correct?

All hints and tips gratefully received
