A good question. What I wonder about, is what happens to a clear coated playflield after a few hundred games.  Does the clear stay perfect forever or does it go like the clear coat on a car? . I'll agree the work is great that is being done, but what may or may not be proven yet is the long term durability of a clearcoated playfield after many many games. ?
Has anyone got any games that have been clearcoated a year or two ago and how are they holding up to BIG regular use game numbers.
Mylar is original and does last. Some will prefer original. We need to see some 2 or 3 year aged clearcoat jobs after lots of games before I could decide with my longterm keepers. (but yes, clearcoat looks the goods, durability ?)

Can anyone help with their knowledge and experience with clearcoated games after a number of years ?

P.S- i just had a close look at some of my sega games, and they do appear to have had some sort of clearcoat done from factory ? not sure if this is the same as todays clearcoats, or slightly different but they have held up like new. We are talking 1998 and 99 models here.

WMS CALLED IT DIAMOND PLATE (  bright and really lifted the colours on the PF)
but
(late) Sega's called it Stealth Finish or Stealth  hardcoat  look on your SST its written on the pf  ( really dull even when the games were new it dulled the art work down...it was friggin crap)

I've had a few Sega pf re- cleared to a WMS like finish  they look fantastic and lift the art work up
