Coolant
I too am using the coolant from NAPA, but I am not having the burining eyes issues at all. I just bought 2 more galons of it. It does leave a film but it's easily cleaned using the coolant itself. We use the blueish tint stuff at work, want to say it's S-122 something. My buddy uses something just like the NAPA stuff in his Mori's, looks the same smells the same, 5 gallon bucket is like $125.
RAD. Yes those are my initials. Idea, design, build, use. It never ends.
