Liquidsquid, you probably have come across this long thread before, but if it helps, go back to the first page and see some pictures and description of how I did it. I found a boat of anytype with a rope across and a person on each end pulling you back and forth is by far the easiest. You soon find that the width of each 'swath' is not that critical. You can seasily see the floating white goo on top and you can decide how thick you want it by how much overlap you do of each 'swath'. I found a hand held fertilizer spreader allowed me to crank a nice even pattern on top of the water. It wasn't that hard if you are just sitting in the boat, mixing part A and B, and cranking the spreader while 2 people on shore keep you in place in your swath and also help keep the speed correct as you go back and forth across.
