Oh it does get really hot, I never melted a hose b/c the hose sticks out far enough away from the body b/c of the quick fitting on its end.
Even so it gets really hot. Im highly considering one of those pump 12vs, alternatively for 300 I can get a 2 gallon tank and 12v comp like we use in our work trucks, it pumps out enough to use an impact for a bit.
