Re: Opinions on 3M Scotchguard paint protection film (aka 3m Clear)
I had it back when I had my audi a4. Paid about $500 installed for the front bumper, mirrors, 1/4 of hood, and fenders. Definitely worth it if you live in an area where you'll get chips. Also, it makes cleaning off road debris, bug guts, tar, etc.. very easy, wipes right off.
For normal upkeep, you wash and wax it just as you would wax your car, just don't use any abrasives/polishes on it. If you already have chips on your front end it's probably not worth it to get the clearbra unless you get the chips fixed first. Otherwise when the film is applied, you'll have air bubbles/bumps where any paint chips are present and it won't look good at all. Applied on fresh paint with no chips=unnoticeable at most angles.
