Color doesn't matter (except for matching the weatherstrip color), there are a couple types that 3M makes. I wish I had them here to confirm the part #'s but here's what I found out. I purchased the 3M black adhesive for my seals along the back of the door glass and had so so results, when I was installing the trunk seal I read the directions (I know, hard to believe) and it called for a specific part #. A trip to the parts store confirmed that there was a Super Strength adhesive, same container, same colors just a different # so it matters. It worked allot better (it was yellow but comes in black as well).
