Quoted from High_End_Pins:800,1200,1500
If you know you have plenty of clear to work with you could go 800,1000,1200,1500.
I don’t like to go finer than 1500 because it is a good final grit for playfields and creates a surface that looks appropriate once properly polished.
Sorry for an uninformed and noob question, but I have a chip in a playfield (wood, art, and clear lifted together near a narrow post) and was told to glue it down and polish it. But I don’t know what should be used or done for the polishing. Any advice? It’s really interesting and educational following along in your work. Thanks for posting it all.
