Removing back window was a treat. All the gaps and channels between the seal and outer trim, and again under the inner trim looks like it was packed with plumbers putty. There was also a white foam strip under the glass but in the seal gap.
Had attack the seal for hours cutting with razor knife and dissect it all. But got the trim out unharmed.
The payoff to plumbers putty I guess is in the condition of the sill and package tray areas.
