I also got all my weatherstripping for my 1974 23 Tsunami restoration from American marine.
I spoke to them last week and they said that they use silicone,to bed the glass.He recommended using a good quality Gen Elec or Dow clear silicone,bedding the glass in first,then installing the weatherstripping.

I made a tool for inserting the weatherstrip,by taking an 1-1/2 flexible putty knife,and rounding the corners a little bit,just to break the sharpness.
It works perfect,just slide it behind the front edge of the rubber,and push,and slide along.It pushes the backside of the rubber into the frames channel, and behind the glass.
