Nice one Gav, do they play any differently? 
Funny you should ask... One of the bestest best Kiss machines ( not the first ever best, but best ever best) i thought played a little slow... PF was nice and shiny.... mmmm i thought... too much wax maybe??? So i emailed my favourite seller who explained everything... see below..
"Imagine its 2010 and youve just been lucky enough to purchase the best if not the bestest ever best KISS pinball machine... you unwrap the box and unroll your BRAND NEW BEST THERE IS overlay. Licking your lips you apply this to the NEWLY rubbed back playfield. Standing back you are amazed at its shiny spongy quality. You surely now know that not only have you just bought the ultimate SUPER BEST KISS but you also have the reassurance that you now have a BRAND NEW PLAYFIELD that has been made BETTER than original because it is PRINTED -NOT OLD TECHNOLOGY SCREENED using the best latest machinery known to man... only YOU the lucky purchaser of this NEVER TO BE REPEATED KISS MACHINE will have the great privilage of playing on its new shiny modern playfield... CONGRATULATIONS!!!!!!"...Well.... nuff said..... Its not slower... its MODERN!
