I presume you are referring to 3m urethane. Much trickier to use than butyl for a rear window with no real up side. Urethane on a vertical window requires rubber blocks in the bead, and mechanical clamping to hold the glass until it cures. If the bead gets too thin, you risk having the glass blow on a good bump. On the other hand, the back glass has no structural load, so you don't lose anything with the less rigid seal that butyl gives you, but get a much easier install in the deal.
