Great work Nino I have done a lot of air brushing and no way could I have done a better job than what you have done. So looks like decal is the way to go in repairs where fine detail is required to make a professional job. If you HAD to air brush this job I reckon it would take twice as long to do as what you did.
I think going down the path of a proper restoration - the mylar would have to be removed for the entire playfield - that would have been a problem, and created more touch up work, then a clear coat to seal the work. I'm afraid that level of restoration is outside my current skillset. Gavin would probably be able to do this - but the hours would be massive.
