I went to Lowes and picked up some play sand last week just to try it out on a small section of my 5 Ton which has many layers of paint. I set it up per instructions and it worked incredibly well on spots where the paint had already peeled off several top coats. I did about 5 square inches in about 6-10 minutes and it took it right down to shiny metal pretty quickly. So I moved on to another spot where there was lots of layers and no peeling just brush marks. I gave up. I think the paint was laughing at me saying is that all you got! I kept the nozzle up close to the paint and it barely took off one layer. Maybe because my truck has many layers of hand painted coats but I can't imagine how anyone could do wheels or anything else with many layers of paint unless they have an incredibly large amount of time, patients, and lots of sand. But I guess it would be awesome on other less challenging surfaces. Oh and by the way, you have to sift the sand! A couple of times I got a larger diameter grain of sand logged in the nozzle. Once that happens water back feeds down the plastic pipe and wets the sand and the hose clogs up. You'll spend the next 20 minutes trying to unclog the hose. Of course this was self inficted. I'm ordering a sifter. I think this is a great product to have around the house for other chores. I believe my power washer is 2,500 psi.
