whenever it rains, somehow leaves all black/dark streaks running down my paint from the bed rails! i mean they come off if i wipe them but still look horrible and a pain to always clean them off after it rains! also the mirrors and rear side windows do it but not as bad. drives me crazy, especially the bed and on white it really stands out and looks terrible. any help to take care of this problem would be sweet. Thank you

 

When you last detailed the truck did you put any tire shine or dressing on them? I did this once and they looked great until it rained. I just kept whiping it off after rains till i had a chance to wash it, then i just scrubbed the plastics real good to try and get all the oil out and it worked.

 

hmmm maybe it is oil from stuff i put on them awhile ago. it looks for like dirt running down. could it come from underneath them?

and your truck came out looking sweet with that BL

 

it could be just that old oil but it might just be the dirt from the rain. just shows up more in those spots because thats where the water tends to flow better down the truck. thanks though man, your truck looks real good too after the new tires and rims. i was about to get the XATs myself but it was cheaper to get the coopers here.

 

yeah i guess i will wait and see and keep cleaning it after the rain until maybe the oils run off of them. and thanks, i love the looks of those cooper stt's. off topic but what shocks you got under there? im in the market for new ones

 

If you have access to a pressure washer try to blast out the stuff in between the bed and the plastic guards. Sometimes it can accumulate dirt in there and it runs out when it rains.

The other option is like someone else mentioned, the dressing you put on the plastic is coming off. Plastic does not absorb dressing, so it is important to wipe off as much excess as possible with a dry towel after application.

 

ProComp es9000, their not bad but not great either. Got 'em on sale from 4WP with a steering stabalizer. Seem to be stiffer than stock, but in a good way. If I had the money I probably would have spent a little more and got something better though. I'd check out Monroe shocks too, never heard one complaint about 'em

 

the pro comps are like 36 per shock. im on a budget haha. im sure they will do much better than my stock shocks at 106,000 miles
