hold on a sec  , i thought i read more than ive read in a lifetime but i dont know what you mean by "my trick with the hole in the paper and spray Poly/thane" thing. Ive gotta find that one.. By the way i tried color matching myself using acrylics  and of course got it close only to find that it dried darker ( i was warned but persisted anyway). lot of green here, little blue there, little white here etc. Haven't tried with enamels but maybe with a little patience i might be able to get it. at least it wont darken on me

I'm one of those strange bastards that begs for help and then insist on trying it myself. So apologies for the mixed signals when i say yeeehhaaa to a small colour matched tin and then wanting to try it myself as well..
