Preval 2 Pack

I came across these a few years ago at Home Depot and I tried them on a few small things that I wanted to paint on my racecar and didn't want to drag out my paint guns and compressor. They're perfect for small jobs, but DO NOT expect professional results. you WILL get orange peel, so make sure that you plan ahead by adding extra material so that you can cut (wet sand) and buff later. My only negative is that they seem to be a little pricey for refills, it would be nice of they were a little cheaper.

Absolutely does not work with latex housepaint. I diluted it according to instructions (3:2 paint:water) and it would not spray at all. Just air coming out. Eventually I diluted it enough to get semi-reliable operation (works about 75% of the time) but I had to dilute paint with equal parts water. At that point, the paint was so thin that it ran and pooled. For brief periods, I was able to get it to work reasonably well, and then it did a good job. But it wouldn't spray for more that a few seconds at a time without clogging, unless I diluted the paint far too much. Works great with water. Might work well with stain or other thin liquids. Absolutely does not work with paint. A waste of money.

I am not a professional refinisher, and until I purchased these, I'd tried only rattle can nitro (stewmac, old masters, and reranch). Those rattle cans did well, but put out larger droplettes, and were prone to throw out larger drops toward the end of the can. If you're looking at this, it's totally worth it. I'm spraying Old Masters Brushing Lacquer, cut 50/50 with lacquer thinner. (I also dabbled with full strength, and 3:1 (lacquer:thinner). I just like it thin for control, as I'm no master! The mist is so fine! It's pressure is low, and smooth. You can mist-on coasts, or lay it a little heavier by going over an area a number of times (I'd get everything wet, wait 3 minutes, and wet it all again, ad nauseum.) This does NOT do the heavy flowing coats of an airgun. It IS much more like any of the small air-brushes you've seen...slow, very fine mist, and low volume put out. But, it's steady, and consistent, and seems to have a larger area of nozzle spray, in comparison to buying the cheapest $40 airbrush. I didn't test the full strength mix on anything, but both of the mixes that were cut with the thinner had a fairly minor orange peel (again, this sprayer doesn't seem to be strong enough to "flow on" a coat, nor am I THAT good with this equipment) But, it's certainly easy to sand out, and orangepeel is even and small grained. With regard to how long a power cartridge lasts, it seems to be somewhat on par with a standard sized rattle-can, and I get about 4 of it's glass jars-full of liquid sprayed, per power canister. It's super easy to control, and even changes pitch a little when it starts getting low on aerosol. Easy peasy. Very much an upgrade over rattle cans, very much cheaper, yet not as unwieldy or up-front cost in comparison to a proper full spray rig. Ya know what, I take it back. You can get dang near a flow coat. It's just slow to get flowing (it requires a number of passes with only 15-30 seconds between passes, and in the shade). In the sun, and with slower passes, you get more orangepeel. All of it is super easy to remedy, either way.

They DO work with cerakote. You’ll see online they don’t, but the trick is to waste half, yes HALF, of the propellant. Just turn it upside down and spray for 10-20 seconds. Any little bit of the propellant that comes up and mixes with the liquid as your spraying clogs the tip. Only letting sit or running acetone through will clear it. Back purging isn’t strong enough. They are good with very matte colors like Burnt bronze, but anything with a sheen it comes out as you’d expect an aerosol to spray a heavy thick liquid. Orange peel. For test pieces or accessories they are irreplaceable for convenience. For any big project or where you need a flat surface invest in a HVLP.

Perfect for spraying thinned nitro lacquer. I used this for clear coat top finish on guitars and it worked very well, better than rattle cans and almost as good as spray guns. The power unit lasted for 6 topcoat of 1 guitar. I was able to drain leftover lacquer from 8 rattle cans to use with the Preval. I may stop using rattle cans since they lose pressure and waste product. I can also add thinner and retarder as desired which is impossible with rattle cans. Sure pro spray equipment is better but it's a hassle to maintain and clean not to mention the over spray.

This thing does not work, I read & re-read the instructions & ended up wearing more paint than anything. Paint spewed out everywhere except on what I wanted to paint. You cannot return, they don't allow it. Even if you paid the shipping back, you still cannot return it. Very disappointed, cause I can't paint well will a brush, but spray should have been pretty easy - it was a custom color & wanted the color to match the front door & there is no spray paint in that particular color. So, BUYER BEWARE. Thank goodness I didn't spend too much on it, I will resell it if I can.

I've used these for years for many applications. It's a great tool for when you don't want to break out the full pressure pot spray gun. Depending on the material you're using you may need to thin a bit more than usual, but once you're dialed in, it sprays evenly and smoothly. I've used it for laquers, enamels and even car paints. Most recently on my Jeep TJ quarter panel; came out awesome. Some folks mention trouble with these units, but most issues are just lack of knowledge with the system. If it's not spraying enough or unevenly, try thinning a bit more or clean the pick up tube screen or replace it (extra one provided in kit). Or sometimes the spray tip is clogged. Try cleaning it or just replace it (extra one provided in the kit). I always keep a couple of these a round the shop, they're great!

This spray device did not work for me. I received 2 of these units, and neither one of them sprayed anything but propellent. I followed the instructions as well as watching several videos on this product regarding proper thinning of paint and other tips to use it. Nothing worked. It is obvious from YouTube videos that it does work for some people some of the time. It is also obvious that to others like me it does not work. As I followed the instructions to the letter and it not working, I obviously received 2 defective units. This is a non-returnable product, and a financial loss. Roll the dice when you order this and hope you get one that functions.

Bought it for the painters that work for me for touch up finishing on site when we don't want to lug around our full spray systems just to touch up. The guys told me it worked really great and could be used on smaller jobs alone. They were very happy.

Nice product

Works well. Watch videos before because if not used correctly, you'll have terrible results. I gave this 4 stars because there is very little useful information provided on how to use. You have to do some research in order to know how to use properly.

These spray bottles can be very unreliable but when they DO work, Spray glazes on pottery well.
