grime!!

[MrAnderson93]

whenever i wash my car or even after it rains, under the the rear windows on my 3 door mk3 golf, near the doorlines, there is always a ugly black streak or two of grime, and somtimes under the rubstrips, they buff off with a bit of quick detailer and a microfibre but id really want to stop them apearing all together, what is causing them? and is there any way to stop them?

its the dirt underneath that is getting wet and running down

the cheeky answer would be clean it properly in the first place 

but unless you remove them or find a way of cleaning behind you'll just need to keep some qd in the boot

OI!!!!! i always clean my car properly a "quick wash" always turns into a four hour mini detail 

and ive tried blasting the jetwash ebhind the rubstrips and it still doesnt work, guess i could take them off and clean, but then how would i get to the windw bits :S

rubber perishes over time and its the surface layer of old rubber that is running down your panels after a wash, you need to clean the rubber back until you hit fresh rubber then get some good quality trim sealant and seal it up.

megs apc or g101 neat on a bit of rag and rub each bit of rubber(quite hard) then rinse off and seal.
