I first saw the 3M clear bra at the car show here in Albany, New York. The guy is an independent business man that goes to the dealers and puts them on preferably before you drive it and get a nick or scratch. He says to do my SKY Red Line will take about six hours. I am pretty sure that is the amount of time he told me. That would mean a further delay but I am impressed enough that I plan to get it done and just pick it up later.
The cost varies from car to car and depending on what you want covered. For my car, doing the basic front bumper, front of hood and mirror area ... $650.
Do a google search for 3M clear bra and watch a clip on how well it protects!
