I gave the ME a shot last night with some 90% Isopropyl Alcohol. What came up was a lot yellow-looking crap. The cracking is very slightly improved, but I didn't want to scrub too hard.I kept checking the ME, and didn't see any paint.
What were these playfields coated with? What is the best product to seal it with?
Also, I need to remove the wooden side rails. I removed the screws from the underside, but it looks like they are also stapled in. Any trick to removing them with no damage? I was going to just gently wiggle them back and forth, until the staples pulled out of the wood, cut the staples off, paint the wood, and then reinstall using the same screws. I don't have a stapler that would shoot staples back in.
