Quoted from dothedoo:Absolutely they did. Easy way to tell is if you have insert wear you can see the clear on the insert will be worn away around the edges. It's noticeable on my Counterforce.
Clarification.....Gottlieb used lacquer, but never made the switch to clear-coat as it is implied in the question - the automotive urethane based system known as Stealth Coat (in DE) and Diamond Plate (Williams)...Capcom didn't name it I don't think.....anyway - thought I'd share as it is believed all 90's pins clear-coated their PF's...and that's not completely accurate....ever notice the wear down by the flippers and such on Gottlieb PF's.....now you know....
