Did the BB spall out a conical hole on the inside of the window? Auto Glass repairers would need the chunk of glass to glue it back in.

You might try Lexel, it's about $6 a tube but works great and is UV compatible. Used it on a window (sealed unit) in the NC mtns. No condensation to date(over 3 years), It's clear as glass, just clean around the repair immediately after application. Auto glass folks use the same stuff and charge a lot more than $6.
*If you can not find Lexel or some other product specifically designed to repair glass, you might try contacting Loctite Corp. They make a wide variety of bonding materials for glass. I have used Loctite 352 and Loctite 363. I think those were the numbers. These were clear materials that cured with UV light. To repair a chip in the glass, I used a .007" thick piece of clear mylar and pressed it flush with the glass to make a mold. I then filled the mold with the Loctite and cured it with UV light. I used an artificial light source, I suppose bright sunlight would work, it would just take longer. After the Loctite was cured, I trimmed the excess flush to the glass with a brand new razor. I did not have very large chips like the BB hole you are contending with. The Loctite was also excellent at bonding glass to glass and metal to glass. Good luck

Is there any hope of reparing a BB hole in a picture window (as they do in car windshields), or is the glass significantly different?
Thanks.
*I called two glass repair services in my area, and both said they could repair the hole. Try the ones near you.
*If its a sealed unit you might get some condensation between the panes in the future.
*I thought they should be able to. I have tried two places that have said no. Did you call auto glass places or window glass places? Where is "your area" if you don't mind me asking.Thanks for your response,Andrew
*It is not a sealed unit. Does that mean that you think it can be done. I have called two places that have said they couldn't do it. Should I keep trying? Thanks,Andrew
*I called auto glass repair facilities. They're able to repair stone damage in windshields, and felt they could also do a picture window.
*Did the BB spall out a conical hole on the inside of the window? Auto Glass repairers would need the chunk of glass to glue it back in.
*I think any glass material in that cone would be shattered and broken up too fine to reglue. The auto glass repairers inject glue into small cracks, but you have an "excavation" not a crack.What you need is some kind of clear epoxy filler, but I don't think the patch will be invisible.How about a flower decal? The Japanese used to repair sojii screens with paper cut out with paper, glue and pinking shears with patches that look like christhanthunums (sp?). They say in a house with small children a thousand christhanthunums grow...
*I had not heard about the christhanthumums before. I will try to pass that one by my wife! It seems easier (and less expensive) than replacing the window.Thanks,Andrew
*A few years back, there was a big controversy because the government spent millions of dollars replacing all the thermopanes in one of their office buildings despite the fact that one of their own people had developed a one-way valve to retrofit to thermopanes with failed seals, lets moisture out but not in or some such thing. They could have saved tens of millions, but the politicos blamed the architects for writing the specs for replacement in such a way that they had no alternative but to blow all that excess tax dollars. Anyways, somewhere in Ottawa is a guy who has a gizmo to stick in your BB hole... I wonder if it ever went into commercial production?
*Well, for what it's worth, My father (as a young lad) used to paint spider webs over cracks in his car windshields. Don't think a Chrisanthimum would have been appropriate for a 30's/40's hotrod.As far as repairing the hole, you may even be able to find a glass repair epoxy at your local auto parts store. I am sure you can find some kind of clear epoxy to fix your window. It may not be perfect again but if you wanted that, you would be replacing the window.on the outside looking in,Pete Draganic
