What puzzles me is that One Day Paint had no trouble at all with the PPG code
for Mallard Blue. He looked the magic number up on a computer, which gave him
the exact formula in his paint system. Looked way too dark wet, still kinda
dark when first sprayed, but after almost 2 years, it looks darn good (if I do
say so myself). Probably would have looked better if I hadn't asked him to
tweak it a bit <g>

There has been a lot of debate over that ... the truth is that it's almost
impossible to make two different paint jobs appear _exactly_ identical, even
with supposedly identical materials. Take two different cans of paint; same
formula, same production line, but made a few days apart; spray them out
side-by-side and they aren't quite identical. The paint makers even warn you to
mix the entire batch together for a single job, because the can-to-can variation
can be noticed sometimes. Even doing that, paint applied one day may not look
the same as the paint applied the next day, especially if there has been a
change in the weather.
So, it all becomes a matter of "how close can you get" and "what does it
matter".

Yes, indeed. Being covered and sealed slows the process down a great deal, but
doesn't stop it. And the different pigments still change differently.

Amen !
