Old Lexan protective paper

[Jim Heffelfinger]

I have a sheet of old Lexan sheeting and it uses a paper/thin film protector on both sides. I am unable to peel the paper off. I have tried http://www.aircraftspruce.com/pages/cs/cleaners_windshield/unmask.php
It does remove the paper - one 1/2 square inch at a time and it skips a lot. Took several hours and 4 ounces to clear a 16 x 10 inch section of side window. Rough on finger nails as they are used to scrape the surface/
Suggestions?

When I was in college I worked as a detailer in a auto dealership, we used acetone to remove the stickers, etc from the windows. Of course that was glass, I'm not sure if acetone would react with lexan or not.

No to Acetone, btw don't get fuel or Windex on Polycarb

Have no idea if it's appropriate for lexan, but what about GooGone? It takes lots of stuff off.

Well, that would explain why the windows around the cashier down at the Quik-e-mart are so cloudy...

I would try heat. A hair drier might work. If not something that takes bumper stickers off cars. Its kinda like a blow dryer but a little hotter.

To remove the strip I put on the bottom of my windshield I use heat. It loosens the glue up enough to peel this strip back. Once removed I use glue remover on a rag and work off all the remaining glue.

If this is on both sides you might only need to heat one side to get both side to peel off.

Try Heat.....

Nice to know it is resistant to cod liver oil and chocolate .... wouldn' you say?

as usual try on a piece of scrap first....
Have not tried goo gone or peanut butter.... YET !

After putting on the goo solvent (I wouldn't use anything like acetone etc though) consider covering and sealing with aluminum foil taped around the edge to minimize evaporation, and let it sit for a day. You could try kerosene but I agree to try a small corner first.

Yeah, i have a suggestion. Ask the people who make the stuff how to clean it before you melt it or dissolve it.

Notice they say you can use kerosene but not acetone, and windex with ammonia is....well, GO READ IT YOURSELF.

My only experience with Lexan (other than flat plates of the stuff put in gas stations & banks) was the back window of my buddy's 66 Cuda that we used to race down at Wentzville. It cracked & glazed over after a couple of years, (cracked really bad in the bends in the back corners of the rear window) he never cleaned it with anything other than water & dishwashing soap.
