Tried doing a search, didn't work. What are my easiest options to repair the missing white paint from the score area on a Williams EM backglass? Is there a kit I can buy consisting of premade semi-translucent vinyl etc? I can't see myself cutting something perfectly after scraping off the remaining white paint. It doesn't have to look perfect, just better than this. I will say, "this" is tremendously better than what I was working with prior to receiving this BG.
Thanks

I've scraped out all the white paint, and applied a piece of thin, white mylar film. Cut out the windows with a sharp blade. Looks great, and is just the right translucency.

I can tell/show you what I attempted for a similar situation, but the method was a bit tedious and not as easy as to get nice results as I might have imagined. Basically, I used an old fashioned razor blade followed by an Exacto blade to scrape off the old white area. The old paint/ink tends to come off in tiny micro flakes which make it hard to get a straight line, so I ended up heating the old paint GENTLY with a hair dryer so it wouldn't be so brittle, and also heating the Exacto blade. Then, I cut out mylar rectangles of precise size and positioned them properly on the back of the score window. Finally, laid down some loose masking (don't want to stick anything to the back of the good parts of the glass) and sprayed a uniform coat of some white enamel onto the back. It wasn't perfect, but I went with it until I bought a new glass.

You might do better if you can find a semi translucent stick-on material like you mentioned and then cutting out the precise rectangles with a sharp blade.

I'd try using some black pinstriping tape to recreate that narrow black border before spraying the white if you're going to use the spray paint method.

Good idea JR. I didn't think of it. My glass had other issues that I was unable to fix, such as 4 or 5 faded areas that sat over top of the antirattle pads. I ended up buying a repro glass a year later.

Well, that's the best solution!

Where did you get the mylar?

I just had a piece laying around.
Probably can get it at a craft store. My brother once used a piece of that stuff that often covers new metal surfaces, like on a new gas grill.
It worked great.

Amazon and Target both carry white contact paper shelf liner

One game I did the method of scraping and then masking off the number windows and spraying with white paint. Looked fine unlit but when lit they weren't quite as smooth white like the ink but a little specky from using a spray can. But I got a repro glass in the machine now anyway. The white mylar method sounds like a better idea.

Sounds like a potential business opportunity for someone to produce white semi-translucent mylar appliques with the pinball score windows already cut out. Of course, different window sizes would present inventory challenges.

That’s a huge improvement. Good job.

I think an even better business opportunity is producing adhesive strips with 0-9 printed on them for score reel repair; particularly the Gottlieb decagon ones! I don't have the technology!
