...and I just happened to have a 2HP 8 gallon compressor. Sure, it's not something you'd see in a body shop, but I got to wondering if I could somehow utilize it to paint my deck.
I began looking around at different spray guns, since of course the gun's demands are what's important. I of course found spray guns that required a substantially high amount of SCFM, something that in a lot of cases I wouldn't achieve unless I got an absolutely massive compressor that wouldn't be easily portable. I went with the 2HP/8 gal because it was the best ratio between portability and power for what I was after, which at the time was mostly nail guns of various sorts.
That being said, I came across a few "detail" guns like this one here:
The 3 SCFM @ 50 PSI is easily do-able with my compressor (5.5 @ 45, 4.5 @ 90), but I haven't seen this gun in person, and I have no idea how these detail guns work. Would I essentially be painting with a super fine line, making it feel like I'm painting with a fat sharpee? Or would this be something worth considering?
Also, perhaps there's a spray gun that isn't very air demanding? A lot of the ones I looked at were geared for automotive painting, which of course strides for perfect evenness, etc... something a little less important when you're painting a wooden deck. Maybe there's hope, assuming this detail gun is a bad idea?
Lastly, when I read on forums about "what size compressor do I get" everybody seems to recommend the absolute largest compressor out there to keep the motor from running all the time which prevents it from "burning up too quick." I never really understood that. Are these motors built to only run in super short bursts? Or is this mentality more accurate with an oilless type of compressor that isn't built to have oil changes and preventative maintenance, etc.?
Thanks for the insight fellas!
