    Who's got some experience with this that can give advice on what to look for in a gun, compressor, running air lines, etc...? After a couple of days of holding down rattle can spray nozzles my damn index finger is numb and I'd be lucky if I could pick my nose at this point.

    The Harbor Freight guns are actually decent for the price, not the best but a good paint gun isn't cheap. You'll also be looking at a pretty large compressor, you'll need around 10cfm @40psi for HVLP guns. No oiler on the compressor, add a drier and a 2nd regulator.

    Disclaimer: I'm by no means a pro at this just know enough to get myself in trouble. It's a pretty large expense unless you're planning on doing a lot of painting. I've got one of these that works great for rattle cans https://www.amazon.com/Rust-Oleum-241526-Comfort-Grip/dp/B0015RJ41I

    Thanks! If I end out going this route, the compressor would be a dual purpose for painting and air tools. Who knows how much painting I'd be doing, but it's nice to have the right tools to (usually) make the job easier and (hopefully) the outcome more professional.

    One of those adapters is already on order lol. That's my interim solution.

    Read up on drying systems on YouTube. You can do a lot with vertical pipe if you hook them up right. it’ll dry out a lot better than a single dryer will

    I think I've seen some multi-stage drying systems at one point. I'm not sure how hard-core that needs to be for my purposes.

    How much painting ? The whole car/truck or just a 1/4 panel? Do you have a 220v connection? What's the budget ?
    Ideally get a 2 stage oiled compressor rated for 100% duty cycle, pex lines, a good oil and water seperator and your hvlp gun of choice. An oiless compressor WILL NOT provide the cfm you need unless you go to a rotary vane compressor (get one designed for dentists if you do). Since you still need a water seperator regardless, save your money and get a really good oil and water seperator.
    If you have the room, you want your compressor located in the shed/workshop -- oil seperator-- copper lines from shed to paintbooth/garage -- second oil seperator with regulator -- pex lines to mulitple drop points and everything in 1/2 inch lines.
    You do not want the compressor in the same area as your paint booth because when it kicks on it will blow dust everywhere.

    That said, I have painted 1/4 panels with a 30gal oiless and it came out just fine....after lots and lots of wet sanding.

    I'm not planning on painting entire vehicles or doing anything professionally, but it would be nice to repaint a panel and other projects if I need to. The compressor would be sitting in the garage. I don't have room anywhere else for it. I don't currently have a 220 line, but I'm planning on wiring the garage for better lighting and installing additional outlets for tools that may need a 220. So it will eventually have one. The budget isn't planned at this point, but $3000 isn't unreasonable.

    Get the smallest foot print compressor with a 2 stage iron oil lubed pump, something like a 60gal Quincy or Ingersol Rand. Even a harbor freight one will probably do just make sure the compressor is rated for 100% duty cycle. Build a cabinet for it to sit inside the garage with intake and exhaust ports .. exhaust to the outside or to an air filter to reduce the dust kicked up. 1/2 PEX lines to mulitple drop points, water trap on your pex line that will do the painting.
    I run multiple water oil seperators so cant help you there on a good single. I am partial to Iwata HVLP Guns, but i am sort of a brand snob... any gun with a good nozzle will do.

    Good luck

    Some great advice above. Volume is everything that's why they're saying 100% duty cycle. A large volume compressor is important as is the water/ oil separator. You definitely need 220 in your garage IMO, many serious tools require 220. My spray gun is a DeVelbiss JGA 502. It was around $300 about 30 yrs ago. Still going strong still made today and still costs about the same. The gun has done candies, pearls, 100s of pieces of furniture in lacquer and even 2 boats in gel coat.

    Nice, I was curious about the duty cycle so thanks for that clarification!
