OK for some of our engineering (A.K.A. rigging) types. This new dissolver just needs to stay wet on the parts surface. So how much would be needed if you rig up a pump, then mount nozzles up top to spray the product for a steady spray. My idea involves an easy rig which would be 1 or 2 blast from a bucket guns mounted in a 55 gallon barrel with a valve on the out side to turn it on and possibly a vent pipe coming out of the top vented to the out side. If some one decides to try this idea, go for it, just let me know if it ends up working for you.
