the previous owner must have used suckshion cups for something....maybe a shade on the plastic rear window of MY00...it is in good shape besides where you can see the round markings left behind.....my question is can I get rid of those by using a heat gun?............probably not huh

 

i would NOT use a heat gun - try mcguyers (sorry spelled wrong) platstic cleaner than some plastic polish first.. if that doesn't work the most heat i would use would be a hair dryer... (or just wait till summer)
