I have a Backpack Mist Sprayer and would like to use this to apply Boracare. Would this sprayer work?
It might but there could be consequences. First, you don't mention the brand of the Back Pack Mister you own. We carry a SOLO BACK PACK FOGGER and it would not be recommended to pump the Boracare formulation through this model. There are just too many expensive parts and too much of a risk that the Boracare formulation will get coagulated which in turn would foul up the sprayer. In the end, the fix would be costly and just not worth the risk/benefit.
