On my side mirrors, there are these wide-angle stick-on mirrors that the previous owner had put on. I have tried several times over the years to remove these things but to no avail. Seriously, I hate them. I want them OFF. But I can't get them off. I have tried Goo Gone, Brake parts cleaner etc but nothing seems to budge them. take a look at this pic. The insert mirror looks like that from me trying to pry it off. Any suggestions here?
