C3 Glass

[Jeff A.]

The side windows on my 70 have been down for years. There are marks that look like water spots on them that won't come off with window cleaner or paint thinner. Any ideas what they are and how to remove them. Thanks

Re: C3 Glass

I have a similiar problem on a '67. I've tried solvents, cleaners and even buffing with a wheel using a rouge compound. (This will buff scratches out of chrome) Nothing touches the marks. I had heard that this might possibly be a reaction of solvent vapors and water that were on the windows during a repaint of the car. I finally replaced all the glass.

Jeff,

You might try using some white vinegar. Keep the surface damp with it for awhile. Also might try something like 3M Imperial Hand Glaze.

Re: C3 Glass

Try this....go to a store that sells fire place inserts. They will sell a prduct that is used to remove the haze from the glass. It is a common occurance with gas fire places. Try a little spot on your glass and see what happens. I have used such products with an electric drill and buffing pad and some water and had great results. It will even take faint scratches out. There are harsher things to do but I would try this first. Terry

Re: C3 Glass

I have heard that you can use "Clay" products that are used to remove deposits on paint to remove deposits on windows as well but I have not actually done it my self.

Re: C3 Glass

Go to a glass shop, or to a catalog company like Eastwood and get you glass polishing rouge and a buffing pad. The rouge, water, buffing pads, and a lot of effort will SOMETIMES remove the water spots. As for scratches, if you can feel them with your fingernail, most likely they will not come out.

Glass scratches

Dick, I have to respectfully disagree.
I have read that "scratches felt with a fingernail will not come out" in the advertising for the glass polishing products. I can tell you it is poppycock!
I took many of those kind of scratches out of the side glass on my 1970 years ago -- when I was a lot younger. The problem is that it took a LOT of time. I have posted the details here several times in the past, but the short story is that I spent 12-16 hours on EACH side --not including time to remove and reinstall the side glass. That total time was in two to three hour segments, and took several weeks per side.
If I were to show you how to tell I have done that work, you could see it, but it is done well enough that if I don't show you where the work was done, you would not see it. Of course, if I show you -- I would have to kill you.
Polishing glass is just like some parts replacement. One has to weigh the points return for the money or effort expended.
