I have had this problem for awhile and decided to see what you guys could come up with. I have a silver 09 unlimited and shot my mopar offroad bumpers with the duplicolor bed armor and loved the results. I eventually decided to do the hardtop in it too so it matched and I like how that came out as well. The problem is after awhile or after it rains I get some black streaking down my silver paint above the rear tire and lift gate. What I end up doing is just cleaning them off with a quick wipe of scratch-x but does anybody have a solution to this to prevent it from happening? Am I the only person that has experienced this? I was thinking if I did a matte clear coat it might help but don't want to spend the time/money if it isn't going to do anything. I'll post pics tomorrow when the sun comes up. Thanks in advance

 

Not sure. I did my diff covers with the brush applied and shot it with the hose pretty good and it didn't run off.

 

I lightly sanded my grill then srayed it, no problems ever

 

How long ago did you bedline it?

 

Can't remember exactly but lets say about 6 months.

 

Probably has to do with the rubberized base. The rubber roof on my motor home which is white also creates black streaks down the sides. They sell a black streak remover at Walmart in the camper section.
