Cinnamon 75 Duster \
I ended up pulling the glass back out. (FYI - I feel this was entirely a sealant problem, gasket is Precision brand from Dantes and fit very well). First pic is from the first time putting glass in. Had to mask everything a second time- not taking any chances with the new vinyl. I left the gasket on the pinchweld at the top and sides. The butyl rope seamed to adhere well where it was forced in tight. The bottom was a different story. It stuck to the metal OK, but there was very little adhesion to the rubber. I removed the rope caulk from there and cleaned that and the inside where the glass goes really well with laquer thinner. I then layed a really heavy bead of butyl liquid caulk from tube (NAPA) in the lower 'shelf'. Just enough that I could see it ooze up the front and under the clips when I pressed it in place. Then set the glass into the bottom of the seal and used plastic HF trim tools to pull (not pry) the gasket over the glass. this worked really good. Note - plastic was a little sharp on the edges, so went over with sandpaper to round so they didnt grab the rubber. A little windex helps to lube it. Since the sun was heading down and it was getting cold at that point, I did not seal the glass right away, but put the zip strips in to make sure it had even pressure for the caulk to set up overnight.
Next day butyl was still soft, so dressed that up a bit so it would not interfere with the trim Then I dried the area out good at the glass edges using rags and compressed air. What worked best was blowing from inside at bottom corners where all the windex settled. Once good and dry- Started at bottom with window-weld urethane and put a small bead under in seal so it squeezed a little out by glass. After zipping bottom and putting the keeper rope around, I scooped off as much excess as possible and cleaned the rest with laquer thinner.
Had rain the following night and I saw a little water inside. So I got out the hose and blasted it. Looks like most of it was still draining from the firewall insulation. I did find one leak. it is a really small drip making it through the shaft of the right wiper pivot. Have seen threads about adding zerks and greasing those, so will probably do that. Just wish I would have known that before puting the dash together....
