I've searched this on the forum and have found differing answers in many posts. I need to remove the glass and reseal them into the frame; not fame to body. What is the recommended sealant: the gooey black butyl stuff or a silicone type product? I also ordered new rubber gaskets, so those will be replaced at the same time.
Thanks,
Rick

Rick,
I was wondering if you and Rachael still had your GMC as I hadn't noted any post from you in awhile. Our stay in Chicago was a lot
of fun and I always get a laugh out of GMC owners when I tell them you had to get a permit for us to park out front of your home and
that it was for a dumpster!
Here's a link to Gary Worbec's presentation on sealants:

I believe it will help with your query.

Two distinct types exist. Can be identified as early and late. Early type
has the latches near the ends of the slider glass. Later type near the
center of the window. Later type has a molded rubber/neoprene/etc lock
strip that inserts from outside the coach. Sun/weather shrinks it over time
so that it hardens and pulls away from the glass. Attempts at sealing,
while keeping the opening features, can best be described as difficult to
impossible. But fair success can be had by using butyl windshield sealant
and forgetting the opening feature. Not the best option in my opinion. New
window lock strip can be installed with butyl sealant on the stationary
glasses with fairly good success. But, the sliders, not so much. Keep the
weep holes cleaned out and the frames tight to the body, and good luck with
the leaky sliders. That's my assessment of it, anyway. The cure? One and
one half GMC dollars. New replacement windows from Jim B. or Jim K. The
kind that open and close on hinges. That is a big investment, but it will
stop those leaks. Now, for the roof seams, bat wing antenna, roof air,
vents, clearance lights, plumbing vents, etc. One baby step at a time, I
guess. Jim B has been known to quip, " Leaks?, just drill larger holes in
the floor than you have in the roof. That way, water will run out faster
than it runs in!".

I never used any sealant. Just used new rubber lock strip.
Did you get your hook back?

Ken, I did get the jack hook. Thanks. A couple of our fixed windows have shifted from their normal position and I need to move them back. My thought was to fully remove them all, reseal the fixed glass into a proper position and install new rubber gaskets. The adhesive on the current fixed glass is the butyl rubber style. I heard folks recommend using that, as well as some recommendations to use a CR Larwence silicon sealant to reinstall the fixed glass. I'm not sure either would be better, but I would like to do this only once, if such an idea is possible. I will pin in the fixed glass with a rivet to prevent it from moving in the future.
Regards,
Rick

Actually, the glass floats in the frames as the body flexes and expands and
contracts with heating and cooling. I'm not too sure the rivet idea is a
good one. Be sure to use a NON-HARDENING SEALANT. I personally have no
desire to have ANY silicone based sealant anywhere near my GMC or my entire
shop for that matter. But, use what you want. Silicone will never hold
paint, and "fish eye" when on surfaces that you are painting.

With regard to the rubber around the outside of the window, I got this tip from Jim Bounds when I replaced my door window: "After installation, paint both the window frame and the rubber at the same time, as the paint will protect the rubber from UV rays and prevent it from shrinking." Three summers of outdoor storage later, the rubber looks exactly the same as when it was installed. I wish I had thought of this when I did all the window trim 10 years ago, as I'm going to be re-doing them all next spring (except for the door window rubber, of course).
