Alrighty then!

Had a go with the isopropyl wetting the magic eraser trick (lower playfield so far) and came up with the following. Not too shabby i think? The only problem with it is that when it had grime, you could hardly see the paint chips, now they stick out like dogs ball (cant see them well in the photo). Oh well, a few more hours of this and i might have something to touch up!!!
