After a while it will turn milky though. Its good while it lasts, but most cars run glass. Most windshield places should be able to get you a glass shield...... Knotty, any suggestions?

it is not as flexible but, I think I could rig something up lol, might have to make it a 2 piece, which would not be too bad, then I could fit it in a big oven and curve it if needed

found this

*********************

Now, when the plexiglass is heated up to forming temperature, about 350F, the material will SHRINK about 2%. But according to the laws of expansion and contraction, the material will also EXPAND when heated. So a fabricator has to be a bit of an artist to attempt this particular job.

But wait - there is no mold. Or is there? Our man Bryan has decided to use the OLD windshield as a mold. It's not a perfect mold - if you lay the heated plexiglass OVER the old windshield, the new one will be slightly bigger. Using the inside as a mold will result in a windshield that is smaller. We decided to use the outside as a mold and then use a heat gun to wrap the sides after the windshield has cooled - a secondary operation.

I saw on a t.v. show where the us air development program re-made a ww2 nazi prototype jet, and they put the new pieces in the oven and pulled them out and formed it to a mold while still warm.  They had many contours to follow on the mold so they ended up making it in several pieces instead of one. So I think if I made a 2 piece I would have ample time to form each piece
