local
Why don't you try to find a local paint manufacturer? Most local companies have the best quality at good prices.
Usually at a local place 100% acrylic actually means it, vs. the big guys where they take out a lot of the good resin and put in cheap vinyl acrylic.
It may be hard to find a local, since all of the chains are buying other paint companies, but it would be worth it to find one! They would be happy to have you!
