    been years so I am way out of date but I have a couple binks model 62's If I remember correctly and it served me well . several years ago I bought a set from eastwood company the newer models with the cup on top of gravity feed one full sise and one small touch up gun in a matched set case couple hundred for the set . I was going to paint a truck for my son but sold the truck so never got to use them . but I have a couple 69 Camaros in the wings waiting .
    like every thing you can go the budget route or go all in and spen a lot of money . I am just a back yard self taught hack . I know there is body shop / painters on here that will check in and give you good advise
    until then do a lot you tube and googling searches
    that's my plain as paint and combinations have changed and so many options I would not know where to start
    I was watching one of the high end car builders shows he said no stress if you mess it up its paint just wipe it off and start over [:0]

    debvliss gravity feed is the way to go, lots easier to use then the pot guns of the past.

    then if your just gonna paint one car an not clean it just hit harbor freight for ten buck an trash it when done

    I've been using a Devilbis HVLP syphon feed for nearly twenty years now. The gun nearly paid for itself when I painted my Thunderbird.

    The HF guns are cheap enough buy three. One for primer, one for paint and if needed the third for a backup or to shoot clearcoat and just toss'em in the trash after each stage.

    If you plan future use the Devilbis is a decent gun that's affordable. Not up to show car standards, but capable of matching dealership quality.

    Have a look around here.

    Whatever gun you wind up with, be sure and put a dryer on the compressor outlet so that you keep water from the compressor out of your lines, gun, and paint. Ask me how I know...[:I]

    I have painted may cars, to include custom jobs.

    Your compressor will do just fine.
    DO NOT GO CHEAP ON A PAINT GUN! If you do, you best have a spare.
    I strongly encourage buying one with a top feed reservoir.
    Make sure your spray pattern is a perfect even fan pattern before you start laying paint.

    I agree make sure you have a dryer water trap on the air line ,
    do some testing on something before doing the top coat even a piece of cardboard to check the flow and pattern . make sure you have the air set to match the gun . primers are more course so that's why most have at least two guns or different tips , all listed above form others are all good tips . also mixing the paint make sure its all the same brand and in proper mixtures . like I said its been at least twenty years since I painted a car but the basics are the same .
    go to you tube watch as many of the how too vids as you think you need to get a good idea , I wish it was around when I did my first paint job it was a learn as I go and asking questions at the paint / auto parts shop [:I][:I]

    funny side note
    cheapest repaint I ever did . my brother had a old vega my dad and I bought for him as his first car 200.00 investment he stopped by a garage sale bought a box full of rustoluim paint gave 5 bucks for it we bought some thinner and masking tape mixed all the paint together it up came out a Richard Petty blue or close to it . for just about 25.00 in material It made the vega a looker from 20 feet [:D][:D]

    Paint guns, there is no right gun there is only favorites. A siphon gun is good for priming but the advances made in HVLP guns far exceeds siphon guns.

    Tips, depends on the paint and pattern, ask questions when buying paints as different paints will need different tips. Also tips change pattern, do you want a large coverage area or small? Depends on what you are painting.

    Compressor is on the small end but will work, remember to have a regulator on the gun itself, DO NOT RUN 90PSI INTO THE GUN!!!! My Snap-On HVLP with the last paint I used only required 4PSI regulated at the gun!! Too much pressure at the gun will cause headaches like reducer failer that evaporates in the air.

    Water traps, do not make the same mistake I did and place them at the compressor. You will still get condensation in the line. The trap needs to be 20' from the compressor. I ran galvanized from the external regulator with a water trap for 25' then another water trap where the hose plugs in. Line condensation will ruin your day.


    Different paints, reducers, hardners require different pressures, tips, spray times ect ect. There is no "one size fits all" when it comes to automotive painting. Research what you are doing well and follow the recomendations. Even the weather dictates what reducers to use, wrong reducers, wrong pressures and tips will give an ugly paint job.

    When I painted my Ford everything went great till color coat, wrong reducer and paint mix caused a grainy finish that can be fixed with lots of wetsanding. I'm going to repaint.

    BSR mentioned hardeners.
    Being a newb, I'd strongly suggest you not shoot catalyzed paints. The hardeners contain isocyanides. That stuffs poison and will strangle ya if you don't have proper ventilation and safety equipment.

    I simplified my condensation control. Started with the best moisture/particulate separators NAPA had. Came straight off the compressor with a 6' whip hose. Soldered fittings to a 15' coil of soft copper tubing that I housed in an old junk cooler just big enough to hold it with room for a 50/50 mix of distilled water and denatured alcohol. Entire cooler (drain, holes for tubing and lid) got sealed up with Permatex 2A and strapped shut with a banding tool.

    Moisture trap is a T of galvanized pipe. Air in on one end of the top cross, air out on the other end and a drain cock in the bottom of the leg.

    Ain't none of it purdy, but it was cheap and it works.

    Since no one has mentioned it. Fisheye additive. It's not expensive, a little goes a long way and it can save major headaches.
    Fisheye additive encapsulates any remaining moisture and raises it to the surface of the paint where it can evaporate/dry without leaving fisheyes.
