Pitting on playfield

[mission65]

I am working on a 1970 playfield and where the ball has rolled over and over the same spot it's left pits of up to a couple of mm.
What is the best way to fill these ready for touching up.
Is there a liquid you can pour in that will level out ?

you could try triple thick spread lawyer. It is acrylic and dries quite quickly. Squirt some into a small container and apply a small drop at a time with a cocktail stick. Leave to dry between drops. Do cover so nothing lint insects etc drop into it while wet. Level of with some wet dry. If you use a dremmel or similar take care you don't take to much off or melt it.
