I have the butyl tape, trim clips and rubber trim, all from 914 Rubber. The aluminum trim, which is black, has been refurbished. Where the glass sets has been cleaned, sanded and primered. I have an expert coming to help me but I cannot see how the rubber trim works. Are the aluminum trim and the rubber trim mutually exclusive? I don’t remember taking off any rubber when the window was removed and the rubber along the bottom of where the window rests seems different. Help.

If you’re talking about the black rubber windshield seal in the link below, it is used as an alternative to the original trim pieces….. not together.

There is a thread or 2 on how to install the rubber version on this site, and 914Rubber has this brief description here:

Thank you. I think I will stay with the aluminum trim. The installer says he uses something different from the old – fashioned sticky tape.

Does anyone have a picture what the install looks like with the rubber in place of the aluminum?

That installer will be using modern urethane adhesive. The stuff is BAD ASSED but you will NEVER be able to remove it again and you will have to use Urethane from then on.

The primer you have already done is NOT the correct stuff for the urethane and that will have to be re-done.

Edit: you haven't primed the frame yet, decide which material you will be using and prime accordingly. The urethane (modern) locks the glass to the frame so tightly that a minor movement breaks the glass. I've seen modern front windsheilds broken by jacking up one side of the car before. The old stuff doesn't do this (but has to be replaced at some point).

Personally, I believe in using the correct stuff. 914 rubber has it.

The rubber looks good. But I think I'll have him use the butyl tape, from 914Rubber, and aluminum trim based on the above response. Will my primered metal be ok for that? It has worked for 55 years!!

A little expensive...

I've got to do both front and rear windows.
Tap your back glass.
Probably its loose.
When I tapped mine, the window actually moved!
Its ready to FALL out. (IMG:style_emoticons/default/sad.gif)

My one of my side windows pulled out of its rubber mounting strip in the regulator.

All of the rubber in anything 50 years old is suspect...

I'm planning on using the urethane window weld to redo both sides.

So, I am prone to use the new stuff as well, just not for the front or rear glass.

Again, thanks for the reply and the link for the primer I need.

I have only 48 hours so even Amazon wasn't going to help. I called the local SafeLite Glass. They'll sell it to me. So, I'll be sanding or scuffing up the area again for the butyl tape tomorrow, Tuesday, for the glass installer who comes Wednesday.

I am replacing the windshield because it had a bad stone chip. Im sure it wasn't original. I will tap the back glass. It may be original. Thanks for the tip.

One more thing: temperature. You need everything to be relatively warm to get the butyl tape to squish and spread out (and get a good adhesion and waterproof seal). It can help to park the car in the warm sun after you do the initial glass installation and then gently but firmly push down all around the glass.

Yes, the butyl must be warm as well as the surfaces it's applied to min 75F. 85+ best!

Success. Greg at All Service Glass from Lima OH is the man. He got the old glass out and then a week later came back for the install. The discussion above was most helpful. THANKS! I primed with the wrong stuff. Sanded it down some. Greg had the right stuff. I kind of demanded the use off butyl tape based on the discussion. They also roughed and primed the glass. I had the 914Rubber plastic trim clips. The pin that goes in the hole was too big. We determined the best diameter and drilled them. Getting the mirror base off the old window required a torch and the glass ended up breaking anyway. The refurbished black aluminum trim went back in perfectly.
