door seal conditioner?

i may get yelled at, but after i wipe down the interior with armor all, i clean / wipe the door seals with it too. 7 years in my scion and not a leak... they still look new

any black pieces external i use black magic "back to black" its a a-m-a-z-i-n-g conditioner.

 

Me too...tried goo gone and it worked a little but ate the rubber...tried back to black and it didn't do anything...tried de-greaser and no luck...tried rubbing alcohol and no change...lol

 

i used to use back-to-black, ...but have switched to using dielectric silicone grease... check the container to see if it contains petroleum distillates, ...as most of the products you get at the auto store contain them - which are generally bad for rubber...
