Alternate suggestion if you are just looking to protect your E32 headlights. I found a place which carries a 40 mil, optically clear film made by 3M(467MP Hi Performance Adhesive). I have now had it on my headlights for the past 15 months and the film is just as clear as when it went on. No seperation from the lens. This is the most economical solution for headlight protection. Each light costs over $100 to replace. The film is available from Chase Technologies. Under $20 for enough film for all four headlights.
