The kool mist 77 leaves a mild tacky coating when dried. It stops rust on my stuff. I've been using 4 ounces to a gallon of distilled water. After it dries I use way oil to lube the machines like normal. But, I stopped using flood coolant so no issues with oil getting into the sump, I run the drains to a bucket. The misters suck coolant from little Sam's Club drinking water bottles. Just drill a hole in the cap, recycling!
I'll try the 2290 next when the 77 is gone at that price. Thanks for the info mksj.
