RE: minor Fogging\hazed window
If you should need to make new windows, say to yourself that the doing is far easier than I can imagine. When needing to do it, I first believed a vac form box was needed. NOT SO.
After some thought, I wondered if a simply gravity mold would work and it in fact worked very well.
Needed of course is a female mold and male plug. Make the female mold identical to the needed window both in size and thickness. Make a male plug about 1/16" smaller and again of the same thickness.
Place a piece of wax paper on a cooky sheet, lay the plug on it and a piece of .015 PETG cut a half inch over size around. On that, lay the female mold directly over the plug and then a flat piece of smooth wood or plywood and on it a weight, keeping the weight centered.
Place in oven on low heat and give it about twenty minutes and the weight will drive the mold down over the plug when the PETG softens. Remove from oven and let partially cool but yet while still warm, unstack and remove from mold and plug.
The molds and plugs can usually be reversed for the other side of the plane. The advantage over a vac box is that it doesn't consume a whole piece of plastic for each window pane.
Hope the polish solves your problem but if not or you ever need a new side window... remember, it is easier than I thought.
