i talked to my rep.

his first comment was aquabase plus paint is used in EUROPE.
he said he hasn't read anything about it on the PPG news source for dealers only. he said this source is regional so it might be used in strict EPA areas like California.
he will check on it and get back to me.

i am not holding my breath on getting info. he is good on tracking down info if i really need it. but this isn't a high needs request and he has a lot of area to cover and only so much time on hand.
