Apply automotive paint with HVLP Spray Gun.


in this video you’ll learn how to apply automotive base coat paint with an HVLP spray gun you will need the following an HVLP spray gun a 1.0 to 1.6 tip is recommended cup size is totally up to you ideally something in the 20 ounce range is going to be best an inline water trap is recommended and air pressure regulator is required an air compressor minimum horsepower one-point-five minimum tank size 3 gallons an air hose minimum length 25 feet all right we got a gold plastic bumper and we’re going to change it to a steel metallic blue first step is wet sand the whole thing with 600 grit all right the wet sanding is done and when you wet sand to prep for base coat what you’re looking for is a dull finish you find any spots that are still shiny all right that’s that’s not going to have the bite for the paint and you got a wet sand those with with your 600 grit and this is our gun and our regulator and are our red water trap here so you want to go hose and then an inline water trap then you want your regulator and you want your gun and you want to use as much plumber’s tape as possible on all these fittings so that you get a very consistent flow of pressure no leaks now dial in your gun with this knob so that with trigger open you’re at about 30 psi this thing’s in good shape all right so what are all these knobs on this gun this actually sets air pressure you want to have it wide open okay sometimes people have this closed and they’re trying to dial in their gun to not get enough pressure like what’s going on and this valve is closed so make sure that it’s as open as possible what’s this particular knob this knob makes your fan larger and more narrow larger and more narrow sort of experiment with this with the fan that you’re whining ideally your fan should be about the length of your excuse me from your pinky to your thumb like that that’s the fan that you want hitting the the object that you’re painting and one last adjustment is this this is going to be your your fluid nozzle okay determined to actually how much paint flows out of the gun as you’re painting generally you’re just going to want to leave it as it is out of the box other pieces of your gun this is your air cap there that should spin freely sometimes when you use this and you put away you don’t clean it well sometimes it’ll get you’ll get stuck you might want to brush this outer rim with a little bit of paint thinner and that usually loosens it up that’s your nozzle your actual paint nozzle your paint nozzle can be removed with this adjustable wrench that comes with your gun here now with the nozzle off you can actually remove the fluid needle but you do have to back out your fluid adjustment screws here in the back and then you’ll find us a spring which gives it tension and if you needed to clean your ear fluid needle that’s how you would get full access to it that goes a needle that goes the adjustment screw of course your cap is it should be removable excuse me your your cup you know if you find paint in these threads or in your air cap or on your nozzle when you disassemble it you do get you do get this this brush either you know fill it up a little paint thinner and you can scrub these areas clean it’s very important that you get all wax and grease off of any panel that you’re painting prior to applying the base coat and you can use our wax and grease remover you could buy this at any auto parts store and here’s here’s the process for decreasing the entire panel we’ll keep a keep a dry one and we’ll keep a wet one let’s look it well with your wax and grease remover get it one good wet wipe followed by a dry wipe just a little note you’re going to see this with your spray gun if you purchase it from us it’s essentially useless it is a filter but it tends to clog and it requires a lot of cleaning I suggest you actually not use this the thing that we sell is already reduced so it’s ready to spray just give it a real good shake this cup is about 12 I think it’s actually 16 ounces so I’m going to fill it to about 2/3 full if you have one of these mesh filters it’s it’s nice it could catch chunks of paint but it’s it’s not totally necessary before you spray your panel once you spray a piece of cardboard just to make sure that the gun spring properly it’s got the size of fan that you’re after wear a respirator not a dust mask this is a 3m 6000 won now I’m going to paint this outside for purposes of the video it’s going to be very well lit but ideally you don’t want paint inside to keep the dust out of your work all right so before I actually start to spray this piece here important to remember that the first third of this trigger is pure air and the purpose of that is so in lower temperatures when you apply your paint you can actually use pure air to accelerate its drawing time probably not going to use this much it’s about 90 degrees out right now but in lower temperatures if you’re having some problems flashing off the paint getting it to dry just use that first third right there to accelerate the drawing how far should your gun be from the panel that you’re panning is a general rule it’s pinkie – thump this looks quite good and this is the advantage of an automotive paint gun versus spray paint you just don’t see striping and clouds it just it’s able to put the paint on so much more evenly it’s only been about five minutes since I’ve painted it let me see if it’s dry to the touch and see it’s it is a 90 degree day but it is it’s dry to touch already within five minutes alright so we turned a gold bumper into a steel blue bumper just curious how much paint we actually used okay now lunch that’s probably that probably only took eight ounces so this stuff goes a long ways we’re going to save it right back into the can now we got to clean this gun and get it ready for clear coat you just tell some automotive paint thinner or in good three four ounces word give it a good shake okay so we get that thinner up to the top of the cup even up to the cap just take an old empty pan pour that thinner out repeat actually this time we’ll run the thinner through the nozzle the gun I’ll dump that one more time here just wipe this down I don’t have to be perfect Oh paint there let’s get the inside of the cup the outside of the cup they’ll need to be perfect on the outside but you can see a lot of that still great paints hanging around more thinner now this is round number three so we should be looking for a clear stream a thinner coming out here it’s still gray now it’s starting to clear up now that’s nice and clear all right one more wipeout of the inside of the cup that’s ready for clearcoat
