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!

I used a 22gal 2 hp 4cfm house compressor and it worked great for doing individual panels. You might run until some issues when trying to do an whole car without a bb Bigger compressor. However I had no issues painting a door and a fender and then a 4Runner hood. The gun was really easy to set up and learn how to use and get a smooth finish without too much difficulty, sprayed my metallics well too. There is some orange peel, but it’ll all sand out. But I was amazed by this little spray gun and think it’s a great value for the price. Especially if you’re new to painting and need to get some practice in before you really invest. I have no doubt someone with a little more skill and practice could get some amazing results.

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.

This is a cheap gun and that is evicenced by the case, be careful when you open it or the hinges will break. The knobs are made of aluminum and could be easily cross threaded. But the job that it did was very good. All I had ever used was a high preassure sprayer and I had no problem getting the hang of distance and movement. This gun cleaned very easily and stored in the case good. All in all I would recommend this gun for the woodworker. Using the larger tip I put polyurethane on a dresser that I had built with no thinning. If you need a gun for heavy use you might look to something a little better but for lighter use I think this gun is worth the money. Jerry

It was my first time using this unit and worked great. All accessories are in the box. There were complaints about the regulator that came with it but I had no problems. I used oil based primer and paint and I would flush out the tank with the thinner( acetone) in this case. The paint can will tell you what thinner you should use. Be sure to dial in the sprayer before painting your project. Came with (2) mini filters which insert into the gun. Worked great. I filtered my paint prior to filling my tank so I had no issues. Be sure to use a viscosity cup. Lookup how to thin paint. This process is very easy once you get informed. The top feed makes a bit difficult to get into tight spots as well if you need to spray overhead. But all worked.
