Its about 3mm crater - slr camera with right lighting makes it look worse than it is but yes I wanted it to be perfect especially the playfield

It would most likey be solvent pop, where the clear was either too thick in the coat or had not flashed before the second coat. Depending on size can be rubbed out but still needs final cut and polish.

Yours could be repaired but would need to be fully stripped and sanded / re-cleared.

Should not have passed QC. Not minor and should be replaced
