Overall the playfield is really nice.
Removed the mylar around the bumpers, and really just a jolly good scrub.
The main point of damage is on the 15 red inserts in front of the mini playfield.
Removed with a heat gun and gentle use of a rubber hammer and socket.
Cleaned, wet sanded on 400 then 1500, followed my novus 2 and buff.
Question - what type of glue are people using to re-fix the inserts.
