The headlights of my GF's Hyundai Santa Fe have 3M guard on them, and they seem to quickly build up a nice coating of dirt from road spray that severely affects visibility - it looked like the lights weren't even on the other night and then I pulled into a gas station and cleaned them and it was like night and day - literally.
Any tips for something to clean / coat the lights with so the build-up takes longer etc?
