you know what you might be right about the square foot thing cause i just did the math and 8 times 4 =32 square feet and you say 2 oz's per square feet so 32 times 2 = 64 divide that by 16 wich is how many oz's in a pound equals 4 meaning if i were to get 2oz's per square feet i would get about four pound wich is what i was shooting for now if i did my math rong please correct me
