I've used them on automotive spot touch up type work with good success. If you're working on an area that's a square foot or so, or square inches... (or buy a lot of them), it works well. Like anything, if you need large coverage, you need real spray equipment. I keep one on the shelf for touch-up stuff, so I guess you'd say I've found them pretty useful. Also, as mentioned before, some of these modern paints are terribly toxic. It's not just what you breath, but keeping it off your skin as well. In addition to the right respirator, Tyvec hooded suites and good gloves are cheap compared to the alternative.
I know the subject of painting has been beaten to death here on the forums, but I was wondering if anybody here used a "Preval" bottle to paint a frame. I didn't find anything in search. For those who are unfamiliar with these things, a "Preval" (that's the brand name) bottle is simply a small glass jar with an aerosol "power unit" screwed to the top. The package they come in shows a bicycle (an old Cannondale mtn bike) that was painted red but I don't know if that was the whole frame or just parts and/or touch-up. You can apparently spray any kind of paint you want instead of doing "can jobs". I work on military vehicles for a defense contractor and I use these everyday at work and they're great for touch up and stenciling. However the mil spec paint I use is flat and I haven't used these bottles for anything else. I asked my team leader if you can buy these retail and he said you can get them at Home Depot. You can also buy the power units separately when they get "spent" and keep using the same jar. Anyway sorry for the long post but I'm wanting to use these on an old Schwinn tandem frame and wanted to see if it would achieve good results and how many power units I have to go through.
I'm really pleased with the way it came out with the preval spray.
This worked fantastic on my car spoiler. Put 4 coats of gloss clear coat I bought from Advance Auto store, and it looks like brand new.
THERE IS NOTHING LIKE IT IN THE MARKET PLACE. I love using Preval sprayers when I can't find the color in an aerosol.
I was looking for something easy to use. Previous paint sprayers clogged and just stopped working. Probably beacause latex paint is impossible to thin. Using an oil based paint, randomly thinned with turpentine, it worked like a charm. The finish was exactly what I was looking to achieve. The directions are pretty simple.
This product works great for what it is. I had a tiny 1 foot square dent that I fixed on my jeep and did not want to set up a spray booth and get the big gun out and make a mess everywhere.
The price of this unit, you sure get a lot for your money. Nice to have all the bottles, glass and plastic, and different size plastic ones. I like all the extra tubes and caps. Assembly is very easy. Be sure to follow the dilution instructions. Very easy to use, just have to get the distance between the object and the sprayer correct. Cleanup is easier than cleaning a brush and less time.
