I saw there is an additive to mix with misting water, does this provide lubrication? Does a water mister conflict with WD40? My observation is that WD40 floats on water so if the water condenses into a pool then it'll float the WD40 off the surface, is this a real-world problem?

The high pressure additives prevent the sticking and keep the
cutting edge sharp. If you are doing a lot of milling in one
spot on aluminum, it heats up. If it gets even moderately hot
it can start to soften considerably. One fix is to take many
light cuts at a faster feed rate to distribute the heat around
the part. Forget the WD40, a real machining coolant will
perform SO much better.
