We've had this sprayer for around a year and had only used it on small projects. That is until we had a lot of extra time at home and decided to tackle painting our kitchen cabinets. And let me make one thing very clear, the only thing I know about painting was picked up by a handful of YouTube videos. We focused on the edges first and then followed with steady 50% overlapping sweeping passes across the big surfaces. I can't tell you if this is correct or not, but our results were outstanding. absolutely! It also comes with a little viscosity cup, which I'll admit, I lost a while back but we ran all our primer and paint through these paint strainers to make sure there was no clumps and everything sprayed great. https://www.amazon.com/gp/product/B000PA09V0/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1XMA Header ImageTCP Global 50 Pack of Paint Strainers with Fine 190 Micron Filter Tips - Premium"Pure Blue" Ultra-Flow Blue Nylon Mesh - Cone Paint Filter Screenamazon.comNow, before jumping right into to slinging paint, my advice would be to go WAY over the top (literally) with your masking and paint booth. Spend the time now, you'll be thankful later. And make sure to wear breathing and eye protection. My wife and I each have one of these by 3M respirators https://www.amazon.com/gp/product/B0009F5KDS/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 and they work perfectly, while not making us overheat like our N95 masks sometimes do. Very reasonable cost when we bought them, but with COVID who knows?Ok, so we removed the doors and set up craft paper covered folding tables inside a plastic sheet room in the garage. Although I wish we would've span it over the top also because the overspray gets everywhere! Also, plan ahead because depending on the size of your kitchen, you're going to need a lot of space, or plan to paint in shifts, but we didn't want to be moving them around too much. Also, get a bunch of the little table tents to prop the panels up off the surface, so you can get a good coat all around. **one more tip for the doors - do the backs first. We primed first, but when it came to paint, we did two coats to the backs until we were happy, then flipped them all and hit the fronts with three coats and are very happy. NO BRUSH STROKES! The main reason for doing backs first is that even if the tents happen to leave small tick marks in the surface, it's on the back side and. you'll never see or focus on them.**Now back inside to do the frames. We went to the trouble of masking the inside of the cabinets and the best results I had was cutting cardboard to just bigger than each opening. I then cut a hole big enough to reach through and tape them in place. The hole is easy to cover back up before spraying. < Not sure that makes sense, but stick with me. With all of that effort yielded, we did get the results we were hoping for, but I think that if I had it to do over again, I would have bought more primer & paint and just shot them inside and out. Also, take EVERYTHING out of the cabinets...no matter which process you follow. Much less stressful, trust me. Truthfully though, this sprayer is so easy to use, and the only odd thing I ran into, was when painting over my head for extended periods of time, I opened the paint reservoir and turned the straw 180 degrees so that it pulled paint from the back instead of front. That'll make more sense when you start working with it. Hope this helps somebody.
