Re: What's best way to clean grime under fender wells?
VERY difficult to clean, and frankly, not worth the effort since it'll stain again the next off-road trip. Nowadays I just spray tire dressing (low gloss) to cover all the discoloration (double coat if necc).
PhilD mentioned Bondo's Restore Black as being effective on all the trim; perhaps will also work for the wheel wells?
