SP-33000 LVLP Gravity Feed Spray Gun

I bought this kit because it came with all three tips, 1.3mm, 1.5mm and 1.7mm. My project is painting all of the interior doors in our home from the existing original wood/varnish to a white semi-gloss, using a water based primer (Zinsser 1-2-3) followed by Olympic water based latex. This is my first spray gun, have never even used one before but am pretty handy with power tools in general. Painting a few doors with a brush and roller made me realize there had to be a better way. After doing some research I decided to go with an "LVLP" type gun because I have a small 2HP porter cable air compressor. The gun seemed well made and came with the 1.3mm tip already installed. I wanted to start with the 1.7mm for the primer paint and was a little surprised that the instruction manual contained no instructions for changing out the tips... after watching a few videos on Youtube I was able to figure it out, and the wrench that came with the kit was handy.After getting the 1.7mm tip installed, I tried spraying the primer without any dilution (water or Floetrol) which was a mistake. The paint just spat out of the gun every few seconds and I could tell the primer just wasn't able to flow fast enough. Remember there is a small filter inside that also restricts flow. I eventually figured out a good ratio of Floetrol to primer (about a shot glass worth per cup) to get the consistency just right and the primer sprayed on nicely. I also figured out the right pressure coming into the gun. The gun comes with its own pressure regulator which is nice. You want to definitely use that gauge, and on the gun you set the air flow control (knob on the bottom of the handle) all the way open, and then on the pressure regulator there is a black plastic knob that pulls out and twists "+" or "-" to increase or decrease the pressure. The gauge has a color code and the needle should be pointing in the white zone. I noticed that my compressor had a little trouble keeping up... in other words, as you pull the trigger to spray the paint the pressure drops and I had to wait just a few seconds for the pressure to come back up. I eventually got the knack of spraying in short bursts to keep the pressure even. If the pressure dropped too much the paint will spray in larger "drops" on the surface which isn't good... the higher pressure is needed to disperse the paint properly.After using the primer, I switched to the latex semi-gloss. The label on the can suggested a "0.015" tip, whereas the primer suggested "0.017" minimum. I decided to stay with the 1.7mm tip on the gun for the semi-gloss and to use the paint straight out of the can with no thinner added. This worked fantastic and I was able to spray a nice coat of semi-gloss... I ended up doing 2-3 coats on the door for a nice smooth finish and was surprised at just how little paint I had to use. Much less than using a brush/roller.Cleaning the gun was easy, and I liked that the kit came with two brushes which is essential. You really need to clean out the paint and "scrub" the tips with the soft brush to remove all the paint from the small air holes. Once I got used to taking apart the gun I was able to get it clean in about 5-10 minutes and then set the parts aside to dry... I just used warm water to clean as I was using water based paint. Some videos on Youtube show using paint thinner.Overall I am very pleased with this purchase, and using the spray gun really makes a difference on the finished product. After doing the interior doors I may tackle the kitchen cabinets that my wife can't stand anymore!

Takes a little adjustment to get into the low pressure settings but does very well.

I've used HVLP air paint guns at my employers quite a bit, but recently upped my game by taking on jobs after hours. I needed a portable air tank that I could lift into my SUV without help, and that meant I was going to have to find a gun that would spray with a low CFPM since portable compressors don't put out a high CFPM. I researched paint guns and portable compressirs for a couple months as I was preparing for my new venture, finally settling on this kit and the 10-gal oil compressor from Harbor Freight.I'd never worked with an LV paint gun before, so I was hoping they would operate the same basic way as an HVLP gun. I was aware that you must move a little slower when laying on the paint, but I was uncertain how the finish would turn out. I needn't have been concerned! The unit has all the same adjustments as an HVLP paint gun, and the finish comes out perfectly! An added bonus is that there is not a lot of overspray, although I recommend you still wear an air mask. This kit came nicely packaged with 2 other needles and nozzles for spraying different viscosities. The plastic box in which it came isn't going to last forever, but will do for now. It also comes with the wrench tool you'll need to remove the parts for cleaning. The gun, the wrench, all the bits and pieces are heavy-duty, quality materials. It feels really good and balanced in the hand. It lays down a beautiful pattern when adjusted to your liking and the only significant difference I've found is that you have to spray with less speed and more control. This gun compares favorably with the professional guns I use at work, and fills my bill 100%. If you're looking for a quality, durable paint gun that can run with a portable compressor, comes with a kit and doesn't cost an arm and a leg, this one is well worth taking a closer look at.

I have a few project cars I'm restoring. I bought this LVLP spray gun in 2017, but the plastic paint cup cracked after the first time I used it. I never got around to replacing it so have been using my usual HVLP guns instead. I just replaced the cup and have been painting with the LVLP gun the last couple days. I'm not sure it would be the best choice for painting an entire car, as it takes more passes to cover an area, but for just about anything else it will become my go-to paint gun from now on. LVLP guns have much less overspray, use much less air and much less paint. I have a decent compressor, so the air usage isn't of much concern to me, but with paint being close to $60 a quart I'm all for using less of it. The best part to me though is having less overspray. I equate the paint volume and pressure to a little more than what you'd experience with a good spray can, but the paint goes on very smoothly, and I feel more in control of how the paint is being laid down. I'll continue to use HVLP for whole-car painting projects, but for everything else this is the way to go.I'll also echo the comments about the nozzle being too tight from the factory. I had to place the gun in a vise and use a 19mm 1/2 drive socket and ratchet to break it loose!I also deducted one star because the plastic paint cracked after one use. I got a nasty surprise the second time I tried to use it. That said, Harbor Freight carries replacement cups that fit. I still consider the gun to be a great value.
