wow. that's rough. too bad.
decals are a pipe dream for this machine. doubt they ever get officially made.
Someone at expo had aftermarket decals on a DE Star wars and it looked swass. maybe that would be the best route to go. find someone to make you a set and create artwork that YOU like.

I'd say leave it and get more pins to go on either side

Look for a trashed ST25th with a better cabinet and do a swap. Then sell the other as a project.

Or post a WTB DESW Cab thread and maybe get lucky. Eventually someone will be parting one out and you'll get a cab. Heck I have a T2 cab I'm giving someone locally. You will never know what out there unless you cast a few lines.

I'd just leave it as is.

As long as it's not flaking lead dust bits all over your house, just enjoy it's character .

Didn't lead paint go away long before 1991? If concerned, spray with clear to seal it then do what overflow said.

That looks bad ass. Like the Star Trek: Mad Max version. I'd have to mask it off a little and shoot some clear on it. Pull the legs, coin door and start and shooter buttons. Triple thick and be done. If you had machines next to it, you would never notice unless there was a pile of paint dust on the floor on either side.

Have you tried Novus?

I would sand it smooth and paint it semi gloss black and play the hell out of it.

Is the inside solid? Any mold on it? If the cabinet is still solid all around, I'm with pinbum. Sand it, paint it a color of your choosing, and play that game! You won't ever get your money back trying to recreate decals, your only other options would be, as others have said, post a wanted ad and maybe someone has a better condition cabinet or maybe you will find an artistic friend who will take a stab at doing some creative artwork.

sand and have someone do a mirror or piano black?

Are you keeping it forever?

If "yes" then get it reworked custom by a detail oriented pinball or custom paint car guy.
If "no" get it sanded and conciser how much time you want to spend, mirror coat (piano finish) take 6-8 coats (so I'm told- repeatedly) and each sanded back -or simi-gloss black for the future owner to art up on their own.

In our lead abatement class, they said for commercial use lead was still popular into the 2000s and is still found today.

For home use 1978.

Yikes.

OK, then I would sand it outdoors with a bunny suit and a real respirator (do not permanently poison your garage), and just spray it semi-gloss black.
