Bra Removal

[larrybard]

Okay, maybe along with the bad jokes I can actually get some helpful advice.

Now that the DE season has ended (at least for me), I thought it would be a good idea to have my car thoroughly cleaned -- for the first time since I bought it several years ago.  I wouldn't have even bothered this year, but decided that as much as possible of the corrosive black brake dust from my track pads ought to be removed before I swap for my second set of wheels with snow tires.

Anyway, one thing I noticed after the car was cleaned was that the clear protective film that protected the rear flanks looked awful -- cracks all over.  Maybe all those cosmetic flaws had been hiding under the dirt.  So I'd like to remove the film.  Don't know what kind it is (3M, etc.).   What's the best way to accomplish this?  Use a heat gun, carefully pry up a corner, then gently tug at an angle?  Or, with film that has been on for several years, is there too great a chance that paint will come off in the process?

Any help would be appreciated.

Thanks,
Larry
