The sprayer that comes with Salt Off really never worked very well for me—seemed to use up the Salt Off really quickly. I picked up this little gem at Home Depot. It’s a garden sprayer, but you can find fine the concentration and the spray. And, there is a “trigger” mechanism instead of the “off”, “rinse” or “Salt Off” choices on the original applicator. This makes it possible to apply the Salt Off in much lower concentrations and almost “spray paint” the product over the surface of the boat. I think the gallon jug of Salt Off will last a lot longer using this sprayer.
