I ordered a larger sized DP spray wax/detailer and bought the suggested sprayer to attach to it, so I am about to give it the final touches and spritz it for the customer and the sprayer doesnt work at all. GRRRRRR!
Check the area where the straw tubing attaches to head, sometimes there is a little movement and cannot create the right amount of suction. As noted, also the nozzle is often in closed setting and needs tuning while priming the spray.
