Normally I wouldn't reply to a crass question like this but ...
I believe the motor is sealed fairly well for splashes and whatever water it would be exposed to in the above mounting location. There is a black plastic cap on the rear of the unit. This cap conceals some wiring and a relay. The switch has a clear soft plastic cover to give it some protection from water. If you want to prolong the life of the compressor doing under-hood duty, you should consider diaelectric grease inside that cap. Put some on the switch, the relay, and the wiring connectors. The motor itself isn't sealed. The red case has cooling slots on all sides and water will get inside and could get to the motor. I didn't open it up past the black plastic cap but I plan to do some additional sealing before it goes back underneath my truck.
As for price/performance, these are a super bargain at $25 and a very good compressor for $70 if you have to pay the higher price. Git 'em while you can.
