Paint Wheel wells?
#4
I power washed the wheel wells, and then took a can of spay on bed liner to each well. It lasted for about a year to a year and a half of abusive (off road, salty roads, water, mud, gravel) driving with one coat before I noticed any peeling. At the two year mark now, and just waiting for winter to end so I can give it a fresh coat.
Edit, realized you were talking about the outer wheel well, I was talking about the inner wheel well.
