Quoted from PlayPin:I thought about that. Some kind of extremely thin plastic would be great to have in there before lifting the playfield. Maybe the next great idea: Mirror blade protector kits. Hang inbetween before lifting the P.F. to prevent scratches.
I haven't installed the mirror blades yet that I got on Black Friday for use in my Tron, but I saw a tip on here somewhere last year to cut posterboard to place in between pf and blades when lifting it, so that's what I was planning on doing. I'll keep watching this thread for other ideas.
I like the anti-rattle tape idea that UKCatsFan76 suggested. Regarding Patofnaud's felt tape idea, I read somewhere on here that it can be too thick, will get pulled off by the lifting and then you'll get tape goo on the blades. But that could be based upon certain pins as some will have wider and some narrower gaps.
