Power Unit, 12 Pack - Replacement Handheld Aerosol Spray Refill 0268

Prevals are like an airbrush for painting. The first thing is shaking the sprayers a lot before you use them and run them through water until you get the sprayer to work. I love them

I received the Preval Sprayer Power Units in proper amount of time. They look just like the originals, which worked great. However, I have not used these yet to see if they work as well.

These work great and delivery was great.

I usually buy these at O'Reilly paint dept - but I needed a large qty. for an exterior ornamental iron job. You should know - these have 'refrigerant' in them. They must be kept UPRIGHT. No telling how they get turned & rolled in shipping - but if you spray one and it spits & sputters that is usually the reason why. If you buy them in a paint dept - KEEP THEM UPRIGHT at all times. I've been using these for about 20 years or longer in my sign biz & anytime I have a small paint job - like under 3x4 ft for ex. I prefer to use to one of these than dragging out my compressor & large spray gun. As I mentioned - I had exterior ornamental iron to paint - 4 welcome signs located at 4 points on hwys thru a small town. I didn't have to load a generator, or compressor. And a large spray gun wastes a lot of expensive paint. I applied black automotive paint to all four ornamental signs using these sprayers which can get closer & tighter, and eliminate a lot of over spray. The glass jar holds about 2 pints. Each sprayer will spray roughly a quart. I premix the amount of paint & activator I know I'll need in a separate cup, then pour thru filter to fill the glass jar, screw on this propellant unit & go to work. If the unit is still half full when I'm done - I clean out the jar, & spray out laquer thinner till the sprayer sprays clear, then hit mineral spirits thru it one time. I leave the tube intact, unscrew it off the jar and stand it up in a clean cup. I turn the clean glass part upside down to store it. Tip: If a sprayer gets ice cold while spraying it's not empty - warm it with your hands or even a hair dryer & shake the glass/unit a little. You can tell when it's empty - it's much lighter, but the spray entirely fades away. This is the best item for touch ups & small jobs when you need a custom colour and/or want to use automotive paint.

We use for onsite touchups all the time, great product.

A good product for smaller repairs. Sprays like paint spray cans if mixed properly.

Great price buying them by the box.

Came exactly as described and works great. Much cheaper buying in bulk this way.
