Preval Spray Unit

About This Item

Mix and spray your own custom stains and finishes. The Preval is a handy alternative when shop spray equipment is unavailable.

The outfit includes a disposable aerosol power unit with siphon, and a removable graduated glass storage jar.

Unlike sealed aerosol cans, it lets you mix and spray up to 16 ounces of stains, sealers or topcoats. For best results, mix, thin and strain the finish before filling the jar, keep the spray nozzle clean, and have a few economical power units on hand for quick replacement.

Not recommended for waterbase finishes.

This is a totally useless, piece of grabage product!

Verified Buyer


I bought this to make a custom purple on a multicolored guitar. I also bought a replacement unit just in case. Followed the instructions to a tee. I went to test it. Nothing. Just air. I switched to the second unit and tested it. It worked. Then I started spraying the onto the white primer and after about 1 minute it stopped spraying. Just air came out. Then the purple paint started to leak out of the bottom onto the red nitro aerosol lacquer that I'd sprayed earlier. Paint job is ruined and now I have to start from scratch, and still have nothing to spray my custom color with. I am beyond livid. I cannot believe the positive reviews on here. I also can't believe this product is allowed to be sold with this lack of quality control. I expect better. It deserves 0 stars!

Worse than worthless

This does not work with lacquer cut 80/20. Did not spray out of the nozzle but eventually leaked around the base and dripped. Ruined my project and will have to sand and start over.

Awesome for shellac prep!!

Verified Buyer


I use shellac on the inside of my classical and flamenco guitars. I used to apply by hand but this cheap spray system is great for that application. It is particularly good for initial color application. I have a professional spray both and gun but this little spray system saves me a lot of time

I did not purchase this item through Stew Mac:

I found this item some time ago at a big box store on clearance. I’ll admit I usually buy shaker cans for finishing my smaller projects and typically use an electric HVLP setup for larger projects. Either way, I do not have a dedicated spray booth.

There is a quick learning curve such as making sure there is material mixed in the aerosol. One or two depressions of the nozzle takes care of this. This step was listed on the boxes directions. This was my first attempt to mix lacquer and thinner together to spray and used a 2:1 ratio for this. That info I believe came from a previously posted review. I had some blushing and had to sand and reapply finish but that was on me. With that in mind, I did use 1 and a half spray units. Maybe it could have been done with one but have an extra spray unit handy. I used this on a Tele style body, a custom pick guard and small repair to the neck.

Bottom line:

I was extremely pleased with this item and would recommend it for future use.

Ok If You Don't Have a Spray Gun

I've done 2 1/2 guitars now with these Preval units. They work but take some practice and patience. I have had to thin my nitrocellulose in order to get decent atomization with them and it's tough to get even coverage. That said, they do work if you stick with it.

Preval Spray Unit

After a little experimentation, I got used to this handy setup pretty quickly. It's a relatively cheap way to go if you're starting out spray painting guitar bodies. It saves you $$$ from not having to purchase a spray gun, air compressor, etc. Good product.

While having custom color orders this unit is very cost affective and saves me time.

Preval - -good and bad

By

Verified Buyer


I have been using Preval units just recently. Liked the video on flash coat and tried them out. Worked well. For small jobs they are very adequate. Not as good as my regular spray equipment-seems to require more sanding. Also, my experience is to recommend not using for Vinyl Sealer application. Even after spraying considerable thinner thru unit it still plugs tube and nozzle.
