This metal gun was built for industrial use by body shops, car dealerships and undercoating professionals yet it can easily be used by any hobbyist or do-it-yourselfer.

Assembled with the undercoating spray cap attached. It can be easily changed to spray cavity wax by changing this spray cap to the quick coupler and attaching the spray nozzle or wands (all included). The mist wand is 5 ft long, the hand held (90°) wand is 30 inches long.

The Pro Gun builds up pressure inside the tank. This pressure allows for the spraying of thicker products and assures that the rust proofing product is atomized at the tip of the wand to provide total coverage inside the cavity. The gun is recommended for both solvent based and waterborne coatings.

Please note that some bed liners/floor coatings contain silica or rubber particles to prevent sliding. These coatings can not be sprayed with the Pro Gun.

The Rustproofing wands included with the Pro Gun are for lighter coatings, i.e., cavity waxes and protective oils and can not be used to spray under coatings. We offer an optional Undercoating wand (Item BS 39). opens in a new windowOrder the Pro Gun Plus if you want to purchase the additional wand.


Upon finishing the task at hand, purge left over product from the wands by pulling the trigger half way. Rinse wand with solvent/water to dissolve product left inside the wands. Always check the MSDS and tech sheets supplied with the product sprayed to make sure you are using an appropriate cleaner.


When spraying cleaning solvents with the gun, ALWAYS close the Air Control Knob (BS19) first. Atomized solvents are extremely flammable. Properly dispose of cleaning solvents as per local regulations.
