Believe it or not, clear (3m brand) packing tape actually works quite nicely as opposed to mylar. Reason being much easier to apply. I once did this to a Capt. Card glass that had large chunks starting to flake off. You can do it one strip at a time, being selective if you are only doing part of the glass. Mylar is much harder to peel and stick in my opinion. I usually do triple thick, but in extreme cases, this method might be considered. Good Luck!
