Hello all, I’ve just undertaken a major cleanup of a neglected Gottlieb Big Hit. I see that it’s got major orange peel texture on the playfield. I’ve been searching everywhere about this and can’t find anything about this happening “naturally” - all mentions of orange peel seem to be related to clear coating. Also there’s serious dirt that naphtha isn’t making any dent in whatsoever, even with a magic eraser. This leads me to wonder if there isn’t a poorly done clear coating, OVER dirt, on this playfield. Any ideas about how to clean this up if so? Thanks!
