  1. Can the GAC 100 be thinned with Airbrush Medium or High Flow Medium to be used in a spray solution for airbrushing? I plan on sealing Ampersand Hardbord before I gesso it.

    • Hi Josh –

      GAC 100 can be sprayed. We would recommend blending with GOLDEN Airbrush Medium, starting at 2 parts GAC 100 to 1 part Airbrush Medium. When faster drying is required, replace the Airbrush Medium with GOLDEN High Flow Medium. We have also recently updated our recommendation around protecting fro Support Induced Discoloration and recognize that while GAC 100 still works for most normal applications, just as it has in the past, that Gloss Medium does have the edge for more extreme applications, such as thick applications of gels or pouring. Depending on your own processes, you can decide which works best for you. Again, for ‘normal’ painting, GAC 100 should be more than fine.
