Installing Windshield

[AirSpeed]

I am getting close to painting my truck and will need to install the windshield. When I had my 69 painted the guy mounted the rubber seal on the windshield and used some small diameter nylon rope in the slot in the rubber to help pull the inner lip over the steel lip in the cab. I was reading an LMC catalog and it recommends installing the rubber seal in the frame then setting the glass into it. Which is the proper way of installing a windshield? Which is easiest? Thanks!

You're supposed to put the rubber on the windshield first, then use the rope to pull the lip over the steel in the cab. Make sure to use lots of silicone spray. I put the top in first because of the 90* corners, then worked my way down. You're going to have to push the rubber onto the lip as you go along. Hope this helps.

Silicone is a no-no around anything thats gonna be painted and don't even mention it around body shop guys they cringe at the thought of it. But if its already painted then maybe ok but...

Imho use anything but silicone.

No, it's not legit silicone in a tube like caulk. It's like WD-40 except it's made to be used on rubber. I would recommend installing the glass after painting though. As long as you have a helper, nothing will get scratched.

I figured that was what you were speaking of and imho I would not use it but ask others for their opinion on paint and silicone spray.

I have always used liquid dish soap. dawn, joy or what ever you have.

maybe they mean putting the metal chrome inside the seal first then the glass and then installing it in the truck?

I was working on a 60 Corvair on a VERY limited budget. I bought a junkyard windshield and found a new seal. My father-in-law said to use silicon to make the install easier. I squeezed the silicon all on the edges of the windshield seal and proceeded to put the whole thing together. What a mess! I didn't know he meant silicon spray! I won't do that again!

I use Goop hand soap for lube. It is thicker and clings in place and doesn't drip off like dish soap.

concentrated car was shop works great to with out watering it down.

As a few have said here, the rubber should be on the glass first and if you have stainless trim, that should go in the rubber before it goes on the windshield. When the "old school" guy installed my winshield he used rope as you suggested. The rope went in the channel, then they set the whole works in the hole. From the inside, he used a small circular motion on the rope to work the rubber over the lip. Every now and again, they would coak the glass in by slapping it with an open hand from the outside. It also works better if the rubber is warm because it softens it up a bit.

i agree with hogdaddy.. we have cars come into the body shop i work at right after they are detailed and what not and no matter if you clean the area real good u will have fish eyes in the paint..

The absolute best rubber lubricant is available from you local electrician supply outlet. They use is to lubricate electrical cables when pulling them through conduits. Ask for cable lubricant. Also it seems to disappear when it dries without any apparent left-over. Fantastic, no silicone problems and no long-term effects on the rubber either.

Thats a great idea never thought of using that stuff

Anyone ever use Ruglyde? The detialing forum mentioned it as a cleaner but it is sold as a lubricant. No silicone in it but it does contain some anti-freeze. As long as were here are there any tips on taking a widshield out without beaking it?

I've used it a lot when installing tires.

Taking the windshield out is easy, just cut the rubber all the way around on the inside, I used a utiliy knife. After you cut the rubber it just pops out. A new gasget is only about twenty bucks and you will probably not want to reuse the old one anyway.

I am an electrician. I had some on my work truck (shh, don't tell the boss) the last time I installed a windshield. It works better than anything else I have ever tried. I think you can actually get it at Home Depot or Lowe's.

I lube the heck out of the rubber with motomaster hand cleaner....works everytime.

I have many tubes of "PERSONAL LUBRICANT" (dont ask why I have 24 tubes of the stuff) It is just like wire pulling lube, its water soluble as well, I am going to have to give it a try (on my windshield) and see how it works!

needing to swap in a new winshield in my 68', last time i did a windshield swap in my 69' when i put it in dry, it leaked on both sides( frame to rubber) and (rubber to glass) i cleaned everything i thought? any help would be cool zw

Just put a new windshield in the 68. Bought a precision gasket left it in the sun through the hot part of the day. With the shield layinging on the tailgate, my brother and I installed the gasket around the perimeter and then installed the chrome- it is much easier this way than trying to install chrome the the glass. I the took a jar of petroleum jelly and slathered the gasket and I mean covered it up packing the channel with the stuff. Then we took a piece of cotton cord roughly 1/4 " in diameter and put into the gasket channel leaving a loop at the top center roughly 8-12 long. On the bottom we left a piece roughly 2/3 feet on each side. My brother got inside and I was outside. We centered the window in the opening and taped around the painted edges at cab line. After the window was centered, we installed the BOTTOM first, applying pressure with open hand. The person on the inside pulls on the bottom cords until they are within 2" of the top corners- this is important! Then pull one side of the loop to the respective corner applying pressure and repeat with the other side. This is per the GM service manual. The one thing you must REMEMBER when pulling on the bottom lift up on the cord, and when pulling on the top pull down on the cord. This is not easy but very do-able. For the record this was our first attempt at installing a windshield and we were done within an hour. You can do this as well, remember these trucks were assembled on a line and the putting together could not be too difficult or it would take too much time. As a side there are no leaks at all, but i would suggest using flowable sealer in the upper and lower corners to make sure that you do not have any. Also if it is any motivation a glass company want $200 to install using my parts with no warrenty, you can do it much cheaper and most will not even do a truck with the chrome trim because it is too hard in the world of glue in parts. Good luck you can do it.
