I got some new weatherstrip to put on my truck after the paint job is done, but not sure what all I need to do to put it in.

I watched the install on my old mustang, and they used a tube of glazing compound in the rubber on both the car side and on the glass side, and I saw their trick with the string to make it easy to pull the rubber through after setting the window in place.

I noticed on my truck that the windshied didn't have any of that glazing compound on either the truck side or the glass side of the old weathership, but the backglass on my truck did stuff (its messy too). The windshield also has this thin strip of foam that goes around the sides and top of the metal frame underneath the seal, but that's it.

What is the purpose of the foam strip? I'd like to take that off too to paint underneath, but it looks like its attached too good, it will easily rip if I try to take it off.

Was the windshield seal designed to just use the rubber, or should I use the glazing compound?

I'd like to do it myself, but don't want any leaks.

Thanks in advane,

Well, after making this post I checked below and saw another post fairly similar and the only advice given was to pay for a pro because amatuers usually break the glass trying to install it.

Sorry, but I don't buy that.

Last time I had glass worked on, it was the backglass of my 68 mustang fastback (hard to find and expensive if you do). I just needed the seal replaced since it still had the original which was cracked and leaking. I ordered the new weatherstrip myself and took the car to a windshield/glass shop to have it changed. The guy removed my original glass, cleaned the channel and coated it with a rust preventative paint and then reinstalled the glass with the new rubber I supplied. It cost me all of $40 for about 2 hours of his time (new rubber was about $20 from a catalog).

Having seen it done on my car, I would have no problem doing the same thing myself next time.

However, as I said in my first post, the windshield of my truck did not have the gooey compound used to seal the weatherstrip, however the shape of the weathership is the same. I just don't know if I should throw the replacement rubber on the glass and install it or if I need to use bedding and glazing compound. I strongly suspect I need to use the compound.

The way the shop did the install was they laid the glass out on some saw horses and cleaned the glass. Then they put the rubber weatherstrip onto the glass. Then they took the bedding and glazing compound and put a bead inside the rubber groove that the metal of the car fits into. Then they took some string and looped that around the weatherstrip in the same groove and had a couple feet of overlap with several feet sticking out. They laid the assembly onto the opening of the car with the string tucked into the inside. Then they slowly pulled on one end of the string and it pulled the rubber lip into the car as they pulled the string around the length of the window. Then they took the bedding and glazing compound and put a bead on the outside lip that the glass fits into. Final step was to clean up any of the compound off the glass and outside of the rubber (its sticky gooey stuff and seemed to get all over everything pretty easy).

Overall, not too hard, and I'd think anybody who was breaking glass on the install probably didn't know about the string technique and was trying to use a screwdriver to pry the rubber through.

Bottom line on my question: Bedding and glazing compound for the windshield or not?

 

I'm sure your truck's windshield install would be the same as my '79 Bronco. You shouldn't have to use any goo. Just use the string trick and some spray silicon for lubrication. I had never done this before but found directions for a windshield install online. My wife helped me (I think she held the windshield while I worked the string). No goo. No breakage. No leaks.

I don't have a clue about your back window.

Good luck. --sean

 

Thanks Sean, that's what I was looking for.
