Awesome diagram, thanks! Now I just want to clarify this:

You will see the center of the sheet sag but don’t overheat or keep it too long or it will create small bubbles in the plastic. When it’s ready, remove it from the oven quickly and place it over your mold. I then used the metal trim that holds the factory headlamp and forced it down the mold quickly. I then held it there while it cooled. I obviously used oven mitts for this but take care to not touch the plastic with your mitts or it will imprint their texture onto your formed plexi. Cut out the excess plastic to fit snuggly but flush with the metal housing trim. |
So place it in the oven.. once it starts to sag in the middle, that's about when you should take it out? Once its out, you placed it over the plaster mold, and used the outer light trim to compress it down over the mold. Correct? How large was the sheet of plexi-glass you used to do this? Not much larger than the metal trim I assume?
