Removing poly from glass

[Mark Tokheim]

Hi,
I have an interesting question. Whats the best way to remove dried General Finishes Seal-A-Cell wipe on poly from glass. Normally I would use a straight razor and just scrape it off. However on this glass there is a UV coating on the glass, so I am not sure I just want to start scraping. Any ideas?
Thanks,
Mark

A UV coating like a film on the inside of car windows or some kind of chemical UV treatment?

If the latter I would try a small area; if it's the film I would not even try...
