I just bought a Porter-Cable Pancake 6 gallon oil-less compressor (model CPFAC2600P). The directions say to open the drain-valve at the base of the tank after each use. I am a hobbyist woodworker and plan on using the compressor occasionally (18 gauge brad-nailer, filling tires, blowing off tools etc). I would prefer to just leave the air in the tank and not have to worry about filling and draining it each time I use it. I understand that this leaves moisture in the tank which can lead to rust and premature wear on the tank but if this means that the tank will last 4 years instead of 5 that’s ok for me. Does anybody have some thoughts on this? By leaving air in the tank, am I drastically reducing the life of the tool and/or creating a safety hazard? I’ve also been looking at all of the posts saying avoid the oil-less compressors and wondering if the oil compressors recommend draining the tanks after every use as well. I still have time to return this compressor if recommended. Thanks

I'm looking for a good dado blade that is between costs anwhere between $100 and $200. Does any one have any suggestions on which brand works best? Thank you.
