Packard Forum Index » Post-War (1946-54)

I am replacing the two piece Windsheild of my 41. The reveal molding is clean and ready to accept the glass and new rubber gasket. I was advised that I should use 3M bedding and glazing compound. I've heard a few different opinions regarding this product. I would like to hear from any Packard owners what you would use. I want to do it correct and want it to last. Thank you

Sorry I can't be of more help but I would say follow what the manufacturer of the rubber gasket recommends. I would say that would be your best bet.

I suspect that these forums are all read by the same people so perhaps it doesn't matter as the split windshield was also used later but it might not hurt to post in the prewar section rather than in the 46-54 section.

For what it's worth later service manuals for cars with split glass do recommend using a body sealer. I don't know what body sealer in that area would correspond to today. Other places in SMs that call for body sealer mean the rope caulk type stuff. Think for a windshield something that flows freely in the gasket and spaces would get in to seal better so unless there is something specific required for your particular gasket I would probably try the Permatex Flowable Silicone Windshield sealant or an equivalent.

I'm sorry, I'm not sure how I posted this in the post war section but "thank you" for bringing it to my attention. My hair went first, I guess now its the mind !!!!

Thank you

The proper sealant is 3M bedding and glazing compound (WindowWeld). It's available at NAPA auto parts and most other name brand stores, though it may be special order since it's not used much on modern cars.

Put it in a caulking gun and consider reinforcing the nozzle/tip with a piece of metal so you can really shove it under the gasket. The best way to seal a gasket windshield is to line the gasket with strip caulk in the channel before installing the gasket on the glass, and then to use the sealer once the glass is installed as well.

Although it was decades ago when I was a teenager, in giving it thought I don't recall using any sealant on the front or rear windows of my 1940 110 and they never leaked.

Don, I believe you are right , it appears that is was designed to seal with the rubber gasket along with the pressure of the garnish molding . I was advised by a supplier to use a little bedding/ glazing compound . No sure what is best but I guess it can't hurt.

If I were to use anything I'd use the appropriate 3M product; I can say I've never used a 3M product that didn't perform to complete satisfaction.
