I'm not having much luck in finding a clear bra at a decent price on line. Others seem to have found them at reasonable prices. Now I need to tell you that I'm one of the last people to figure out the (you) thing, so type slow so I'll understand. Grasshopper, winner of the Prius Chat slooooooossst thinker.
Are you going to do the install yourself? You can get the kit from eBay for $175 or 185 as I recall. If you're going to have it installed by a professional in your area, just go get a jar of vasoline and have them quote the film and installation.
