compressor size
So I'm finally going to stop asking for favors and paint my own way now. I do have some experience spraying but only on company equipment. I'm going to be painting my race bike fairings only, no cars whatsoever. What size compressor tank do you think i can get away with? (I have searched but didn't find anything in relation to the size of my projects).

Re: compressor size
Size of the tank doesn't matter all that much, the best thing to do is pick out your gun and go with a compressor that will supply the CFMs/PSI for the gun.
Just for example, I use a 19 CFM @ 125 PSI 80 gallon compressor to paint cars, so 1/2 of that might be about your range...

The HVLP's I've seen require 5 to 15 CFM, although compressors that can supply above 5-7 CFM start to get pretty expensive.

Re: compressor size
Holy crap 90 @ 125 is MASSIVE. I think you'll be hard-pressed to find even a 45 CFM compressor in anything less than a huge 240-volt or even gasoline-powered compressor. If you can find one that's electric it'll likely require a special dedicated circuit in your garage that you'll need an electrician to install.

I did have to run a dedicated 240 outlet though

Re: compressor size
lol yeah I was gonna say 90 CFM compressors are like those huge diesel-powered ones on trailers that you can rent for hundreds of bucks a day.
I looked at several guns last night and most required 10-15 CFM at some low PSI like 25 (HVLP guns, high volume low pressure, so lots of air but at low pressure).
My 26 gallon 115-volt Craftsman upright only supplies about 6.5 at 90, which is plenty for my pneumatic tools but wouldn't be sufficient for a good HVLP.
