I installed a clear bra on my Crossfire myself. It's not exactly easy to do, but not quite as hard as I thought. I made sure I purchased the type with the "ribs" cut out. Much easier to apply as opposed to working each rib with the bra (that doesn't sound right). I also purchased several clear bras from Xtreamcity for my other cars. This is the outfit that pushes these on eBay. I have not yet used their bra but their prices are substantially less then the 3M version and the quility is close to 3M's (might be a bit thinner). Keep in mind that the eBay ones do not have the ribs cut out but do cover more area of the hood then the 3M version I used. Lots of patience is in order here for do it your-selvers.
