Did a search but didn't see anything pop up though I'm sure this must have been discussed before.
What is the considered consensus on playfield touch ups of EM games?
I've got an Aladdin's Castle that I've managed to mechanically tune up quite nicely with forum help. The playfield has some planking, a few wear spots around keylines and common ball tracks, some insert cupping, etc. Visually nothing too bad, looks nice and I would probably be ok with it as is, except I'm worried the roughness will cause the ball to tear it up more and of course it plays slower with those issues.
So... I'm thinking of clear coating. Question is whether to touch up first or not. In general when clear coating for playability would you want to always touch up the playfield first or do some of you like to leave the original battle scars? Assume I'm not talking about extreme playfield damage whatever that means to you.
