Clean & wax, new balls, replace rubber. Home use won't put enough plays on it to make a difference.

Oh, & align those flippers

I wouldn't clear coat it unless it was one of my favorite games and wanted it to look nice.

Do what dasvis suggested or go 'whole hog'. I would never recommend that a playfield be clear-coated without all of the following done because you would be 'locking-in' the dirt and planking:

It would need to have all parts removed from the upper playfield, Magic Eraser used to remove the crud in the pre-planking and touch-ups to fill in the planking *before* clear-coating. It would take me 2-3 weeks to do and requires some experience to get it right - and I am still not very good at it. It might be a good summer project for you if you want to learn how to do those tasks, but give yourself at least four weeks to finish if you want to take on this challenge.

Check out this article if you want to see what I did to clear a Williams game from that era:

If it was mine I would either leave it as it is , or use Clear coat and use createx paints to restore it. Subsequent layers of clear would level the play field and remove the planking.
If you just cleared it without touching up it would not look ok.
Judging by the photos it would not be so hard and you will be thrilled with the end result

I wouldn’t. (And I restore/clear coat many playfields of all eras) I’d clean and wax and enjoy.

I beg to differ man, that pf would have so much more depth to the black spacey areas cleared! Check out this FP pf I did a while ago...

What wax are you guys using on EMs these days? I am looking to clean and wax a Space Mission playfield.
It's not great, but not worth the time to touch up and clear.

I’m using Mothers California Gold Wax Paste on my EMs and early SS pins. It comes in a 12 ounce tin for about $20. I got mine at Pep Boys. It seems to be a good combination of price and quality. Carnauba wax gets the most recommendations from Pinsiders. Whether you go with Mother’s or another brand, make sure that it doesn’t contain any cleaners!

Dudes if you've ever used floor wax then you will appreciate one grand blitz wax except for the fact that's its actually good for a pf being mostly 50/50 carnuba & beeswax. You can multi layer it and its virtually no residue and dries crystal clear.
