I'm wondering what the best way is to prevent further damage to the clearcoat and base paint? I am considering 3M front bumber films. However, they do not cover the hood where I am noticing nicks in the paint from FOD (a.k.a. road debris). Has anyone ever tried clearcoat spray from do it yourself car washes, or does it peel away/turn yellow too quickly? Should I just get it resprayed by a detail shop once it gets bad enough? I would buy touch up paint but there are hundreds of < 1 mm nicks on my hood. Plus I'm more interested in preventing further damage vs fixing as I go. Any help would be appreciated.
