On the router, it just wants to load up and melt/weld chips. I'm thinking a 2-flute would give better chip evacuation.

Currently, our coolant system on the router is a student and a spray bottle of WD40.
David,

Like Adam we also use a mister non stop. Your issue is using the WD-40 squirt bottle. Its a waste of time, we did that for a few weeks until we got tired of endmills gumming up and wasting our money.

What we also do is a run 2 airlines + the mister. So two airlines are blowing away the chips so your not recutting chips. The mister keeps the endmill from gumming up.

This is the one we have, bought it off of ebay for ~$40 bucks.
