Well, I’m working on two playfields for the same machine. By nature of Gottlieb’s System 3 manufacturing process they both suffered from massive checking, impact related paint damage hidden under Mylar (long story) and flaking Clear + paint under the posts (Amplified when removed).
I brushed most of the coats on. Globbed mounds of Varathane inarticulately over imperfections. Wet sanded it between coats. Just slathered it thick.
And the final coat was me pissed off and applied so thick the sucker looked like it was covered in white sauce.
Let that cure a week, gave it a light rub down.
Let that cure two weeks and gave it a 400 (in parts) -> 600 -> 1000 wet sand. Naphtha wipe downs. Magic eraser lubed with Naphta somewhere in there. Got a $15 3” orbital foam pad polishing kit for my right angle drill. Four grits of polish. Went to town.
Other than all the damage and funky touch up frozen under all that ice, it looks killer.
My say is that as long as you’re mindful of bubbles and fisheyes on your last coat, it’s really going to come down to curing and cutting. Smooth as heck and hard.
My regret is that I didn’t remove all the old clear.
Now the next one (the good one) I’ll be a bit more careful with.4CCE30A7-F694-4027-8E10-55C0C1F941B7 (resized).jpeg
