Roger,

MAS Cool Cure can and does blush just like other epoxy systems. In our experiance it blushes about 30% of the time. Its the MAS slow that does not blush. That's why we ship slow as standard and CoolCure only on demand. But there is still a huge advantage to using either MAS system - the viscosity is very low which we find makes wetting out cloth super easy and the results are clear; no white areas or 'glass fibers show.
