Quoted from Grangeomatic:Hmmm...I've read that repair guide several times, but somehow forgot about that Saran Wrap idea, or maybe just blocked it out because I didn't think my backglass was bad enough to need it. Thanks for the reminder!
If you go the Saran Wrap route, be sure to give it a few, to several days to fully cure... Then the Saran Wrap will come right off.
