Roger that! I worked with Aeropoxy in my garage (connected to my house) for several years, doing large layups, and never a whimper from my wife or daughters. But just let me spray paint a metal fitting or open a can of solvent and I'd hear about it within 5 minutes. Aeropoxy really is mild. >I don't think a pump can match that kind of accuracy, >especially after it gets a few years on it. The pumps used with West Systems are like the ketchup and mustard dispensers at the burger place... you have one pump per container, pump down on each and get a shot of each. The stroke on each pump (resin and hardner) are different, as are the plunger sizes, so you just pump equal pumps of each and get a perfect ratio every time. It's not the metering type of pump that draws from two containers into one outlet. I use the West System pumps for my Aeropoxy (with the proper size pumps to get the exact Aeropoxy ratio). I love it. You pump as much or as little as you need, no weighing, no eyeballing. If you're at the end of a layup and haven't mixed enough, you just walk over and pump some more and mix it up... again, no mess and no weighing. As someone else mentioned, you just need to make sure to keep the containers full so you don't suck air into the pumps and not get a full stroke of the pump.
