Lucan 196 Report post Posted April 13, 2011 Can anyone tell me what the black goop on the back of E36 door cards is? I'd like to say it's some kind of urethane but what is it really called? Cleaners want to know what that black sh** is on my brand new carpet is so they can get rid of it. Cheers Quote Share this post Link to post Share on other sites
