12 tubes? How big is a tube? is it a standard calk tube?

I just did a shell off and I bought 5 tubes of Vulkem. sealed the perimiter when I put the shell on. I have redone several seams on the roof.most of the gutters. I still have 1.25 tubes left. I should have plenty to replace my windows (the frames) in a couple weeks.

I have a cargo trailer (Enclosed Car Carrier) and thought that I would go ahead and seal it with Sikafflex too. Hope I have enough. If I have some left over that is a good thing too as you never know when you may need some and it has a shelf life of 12 months.
