i am a huge fan of the clear bras ... had one on my crossfire for 4 years... i have installed them on cars since the late 90's. most of the older film/products turn yellow over time (must noticeable on white cars). the newer products have improved the discoloring issue. i highly recommend an avery or 3M product.

xpel.com is a great company and shows an illustration of the patterns for each application. be certain to view one's work before committing to a particular installer. this is an art ... not all installers are created equal...
