I'm not a fan of clear bras. I had a 3M clear bra put on my 2005 RX 330 when it was new. The installation was great and the bra looked awesome for about two years. After you washed it, the bra would shine along with the rest of the car. I was very careful with the bra as to not get any wax on it or scratch it. I had the car for 3 and a half years and 60,000 miles before I got rid of it. By that time, the clear bra had developed a milky look to it. When I would wash it, it almost looked as if I forgot to wash the clear bra and the rest of the car shined like a new penny. It wasn't that bad and looked OK I guess, but I was starting to consider peeling the bra off. Now that I have a new 2008 IS 250, I think I'll skip the bra. I think I'll just try my luck with the paint chips. My suggestion is to pick the lesser of two evils - paint chips or a milky clear bra in 3-5 years.
