I just paid to have my front bumper wrapped with paint protection film (PPF) as I have no confidence in wrapping the bumper myself. Though I want to wrap the front hood also, as you need to press pretty hard to close the hood, and I can see myself scratching it up pretty quickly. Surprising the shop charges even more to wrap the whole front hood, at $670 vs the $400 for the bumper. So I looked into DIY as the hood is very straight forward. If I try to install the PPF myself, a pre-cut sheet of 3M film designed for the M3’s hood cost $299 - $400. Then I found that you can buy a bulk piece of 3M film for $120 at the size of 60” x 48”. The height of the front hood is only 44 inches long so this might just work. All sellers on eBay seem to sell at this price. While I’m at it, I’m thinking of getting more films putting more PPF on the door edges, the rear view mirror housing and the bottom door well also. Also debating whether to wrap the whole trunk or just the top side. Whether this is a good idea or not I’ll soon find out. Will update with install detail and results. Hopefully some of you will find this useful. Do you guys have suggestions on where else I should apply some PPF on the M3?
