Baked on plastic

[Coopers ST]

A friend was in a accident and as a result a window was broken. The tow company put plastic over the side and left it that way. The plastic baked on and stuck to the paint. It flakes off if you pick at it without damage to the car. What can be sprayed on to help speed the process of removing the remaining bits?

Thanks

I would use WD-40 and a plastic razor blade

If the window has been replaced you can try a psi washer (not too close or super high psi) and see if that helps out and makes it any easier/faster. All other comments above should assist in the removal as well...

The window was replaced with a different car. This is on a Miata hardtop that was save do from the old car and put on the new one.
