Sealers AA-6 and AA-7 are water-based acrylic coatings
specifically designed for use on Design-Cast surfaces. They have
low viscosities and thus give good surface penetration.
The only difference between the two sealers is that AA-6 dries to a matte
finish, and AA-7 dries glossy. Either sealer can also be used as
a patina vehicle for a variety of weather-stable pigments.
