LOL, thats funny, I had the same kind of tube in my brown van, it was for "Panama Brown" the top color of my 7 passenger van. Luckily I had it because my color codes behind my backseat are WRONG, they say my van should be PASTEL WHITE and AGATE BROWN, neither of which are on my van!
Is it all dryed up and goopy? the tube I had was LONG past its useful life.
