I have no experience with MAS epoxy, I am using the System 3 that came with my Pygmy kits. Based on reading I did before buying the kits it appears that the lack of blush you get from the MAS epoxy is a result of the slow cure hardener they ship as standard. System 3 indicates that their slow hardener also produces little or no blush. When you switched to the cold cure (fast) hardener blush became an issue again. -- Don Lueder
