GAC 800 is now also sold as Gloss Color Pouring Medium. It is the exact same product, just a different name. (And there is also now a Matte Color Pouring Medium.)

GOLDEN GAC (short for Golden Artist Colors) Specialty Acrylic Polymers are based on 100% acrylic polymer emulsions. The GACs are useful as mediums or modifiers of acrylic paints. GACs can be blended with GOLDEN Acrylic Paints to extend the paint, regulate transparency, create glazes, increase gloss, reduce viscosity or improve adhesion and film integrity. The GAC polymers can also be used for binding pigment solids for various effects and surfaces. Unlike the other GOLDEN Mediums and Gels, GAC Acrylic Polymers have only a minimum amount of thickeners, levelers, defoamers and surfactants to ensure good film formation.
GAC 800 Acrylic
A liquid acrylic polymer emulsion that does not craze in pours/puddles. That is to say that it dries with the same uniform surface and dimensional integrity as when wet (other GACs will craze, developing shrinkage crevices running across the surface). Dries with good gloss and flexibility, but only moderate clarity. Useful to increase adhesion to chalky surfaces.
