Is it possible to polish scratches out of playfield glass?

try a glass shop, with the diy part, I think hell would freeze over before you got any results.
I have tried on crt's with no gain. just my experience. maybe shop for a part out with good glass???

I had playfield glass cut and tempered at a local glass shop and it was not that expensive, about $40. It was done elsewhere and shipped in, so it took about a week. In other words, I wouldn't rule out getting a piece of glass made.

I think there is art screened on the underside of the glass, well not art but the black masking around the border?

New glass is the way to go. I don't think buffing it out would be cost effective even if it could be done. Yes, that shape is probably more expensive than a rectangle, my local glass shop will do octagons, kidney shaped, drill, tempered, whatever I want (I just don't know about the masking part) I had them cut new glass for my Space Invaders wide body, and it is still cheaper than buying and shipping glass.

As far as the glass, most glass shops can probably match that shape without too much problem. The masking on the other hand would be the issue. If it's just a black masking with no artwork or text you could probably do it yourself with black adhesive vinyl. Or possibly mask and spray paint it with paint and then a clearcoat.

You can definitely get the scratches out but could take several hours depending on how many there are. It requires a special polishing grit and pad that would attach to a variable speed grinder. I have restored many windshields using this method.

Give it about 5 years.... Your kids will fix your OCD for you..... The glass will be the least of your concerns once you see all of the cool artwork they draw on the sides of your machines to help you out...

You could try a kit out like this-

The glass is tempered, so the glass shop will probably charge you .60 cents per inch of scratch to polish out any scratches.

That's what it comes down to:. what you can live with. If theres a few minor scratches, I tend to ignore them. I can't seem to keep everything nice (read:kids, pets, my own buffoonery.). If there is a lot and/or really noticeable, it's worth it to correct.

Not sure you can polish tempered glass as it is under pressure and can break when the pressure is released. Make a pattern of the glass and have the glass shop cut it and send it out to be tempered. I worked in commercial glass but we did not do anything but windows and doors but I have popped a lot of tempered glass on my day.

The Eastwood company sells automotive glass polishing kits, never tried but I herd it works.

I am tying to get my Night Moves up and running and I also have scratched up glass. I am interested in seeing what you come up with! The good thing about having non perfect glass is that you aren't as worried about putting something on the glass which is so tempting on the cocktail table games!

Let us know what you come up with.
My Caribean Cruise has some scratches in the glass that I could do without.
