I"ve been using Omni MTK acrylic Urathane with the MH 167 catalyst. It says on the can, "Use entire contents within 14 days after opening". I only used a smiggion for just a repair panel and probably won"t be painting again until summer. Does that instruction mean that I throw the rest away, or what is the result if I use some of it six months from now? And, how critical is humidity in using paint? I notice too, that the MP175 catalyst used with the MP170 epoxy primer that seems to be a favorite on this forum has Isopropyl alcohol in the formula. I was not aware of the health effects of the iso"s until I started reading this forum. What are the health effects, and how soon do they show up. Is there a remedy?
