I had the exact same dilemma doing a full resto on mine. Everything else I'm doing and on any other pin I'd do the playfield work myself but Spirit being Spirit I just didn't want to risk doing it myself. I ended up doing what I was confident in and getting rid of all the mylar and it's residue (the operator had covered the entire playfield with it and it came off without taking paint) and giving it a good clean and wax. It's never going to get significant games played on it that will cause damage and down the line if I want to commit to a professional playfield restore and clear at least the mylar is gone.

I did touch up the black around the playfield window but the operator's mylar really did a great job at protecting the playfield. Good luck on the journey! If you need any pictures as you go along I'm happy to help.

They came like that on mine assume the blue and green was all that was on hand when it came to replacing. I've since switched them out with all new spot target assemblies in the correct colors, B-A-L-L all in white, and 1-2-3-4 all in yellow. I just used the flyers as the source of truth on this.

I believe the spinner motor / assembly for black hole is the same. Here a post about another option for it if needed https://groups.google.com/forum/#!topic/rec.games.pinball/c7AdfRmK0ZM
