The modern tendency is to bond the major screens into place with a permanent slightly flexible mastic. This has 2 advantages:
1) There is no 'rubber' to harden
2) The glass can now used as a stressed member permitting the use of thinner 'A' and 'C' posts.
The downside is that a cracked front or rear screen cannot be left for long without the stresses shattering it sooner or later. Usually sooner.
On the old system I've removed and replaced more front and rear screens than I can count. Removal was child's play as all you needed to do was carefully remove the chromed trim strip, winkle out the locking 'rubber band' in the front of the seal, followed by laying in each front seat in turn and gently booting it out (hobnail boots not required). virtually all the time there would be a soft, non-setting mastic holding the rubber in place so it was common practice to run the tip of a flat screwdriver all round the seal inside & out before deploying 'feet 1.0'. A cushion of a thick, soft material laid on the bonnet meant that the task could be performed by just one person.
Replacing/refitting the screen was a little more complicated and usually required 2 people to get right. One would do all the fine work of fiddling the main seal into place while the other just leaned on the bits already fitted to stop them popping out again as the first person worked his/her way around the edges. Contrary to popular opinion glass is flexible - just - which means that it will distort enough to make DIY refitting a lot easier than it would be if the glass was completely rigid
