Rick;
to save the "paint" (actually printers' ink ,screen printed onto the glass), buy triple thick crystal clear glaze (#0500) by krylon.
this is actually a thicker spray on clear coat (in a spray can). China-mart has it ,& think the Depot" just started to sell it.
Never use a basic clear coat !!!! it's to thin & takes to long to dry , in the mean time, it will dissolve / liquefy the ink & it will start to run together .
Treat it like any other clear coat or paint, hold it 10 inch to 12 inch away from the glass BUT, spray it straight on , not on an angle , or you might blow off a piece that has lifted. to hold down a piece that has lifted..... spray the whole thing , then use quality shrink wrap over the area (s) , then a "heavy item" on top of that. the clear coat will not adhere to the "wrap". but will take longer to dry ,ect.
2 or 3 coats should be more than good. now the open areas with no ink (score number areas), should be taped off ahead of time OR use a razor blade later to scrap off the clear coat.... it won't be so "CLEAR" but, foggy looking. Do NOT cut the ink with the razor , before or after.... it will flak off in pieces. to cut this ink you would need to have the blade very hot to slice through it. of course you don't need to do any of this part.
there is / was a "commercial" brand of stuff some guy in the pinball restoration world made, & a few years after being out,almost every one who bought it curses this guys name now. it eventually destroyed every one's ink.
google "restoring paint on glass , pinball machines". (or some version of that...). you will find a Very nice step by step lay out on what to do, ect. ,by a guy who has restored tons of "painted glass" over the years.(sorry, don't recall the site.).
now touching up any "paint loss", is very much a Big pain in the butt & usually Not worth doing. color matching is almost impossible.
I had to do this on my Keeney's super bonus bell & my A.C.Evans bang tails glass; both saving it & filling in the missing areas.
hope this helps !! may have saved the site = ??? if I can find it.

P.S. , looks like a fun gaming machine to play, nice find !
