Correct. Because of the friction involved, you will need to cool it with water while you polish.Good thread. Looks like a fairly involved process tho...
I've also heard that when working with glass you have to give it sufficient time to cool off naturally and avoid getting it too hot, otherwise you may end up cracking the very piece you're trying to fix.
Use a exacto/shaving blade/knife and scrape it off with a heatgun. Use Goo gone, acetone, paint thinner or any of that combination to remove any adhesive gunk left over. Of course, be careful not to use this on your paint. A messy job and really tests your patience...How about cleaning up lights with XPEL/similar protection on them? Mine have some sort of plastic protector on 'em from the previous owner, and the protector is getting a touch yellow and hazy, plus some smallish cracks.
Should I just pull it off and run the lenses bare? Buy new protection (ugh, expensive)? Or is there a way to clean up the plastic protector stuff?
(How the heck do you even remove the stuff?)
