OK, it is Wednesday. I almost forgot to hang the tarp and hit it with the water hose. But i did it. I started with a light hosing, no run, no chipping, no rubbing off while wet (That i could see). Went to a hard hitting with the hose from about 6 feet away. Same thing, no runs, no chipping, no rubbing off while wet (that i could see). Then went hard hitting from about 6 inches away. Same thing, no runs, no chipping, no rubbing off while wet (that i could see). I think this type of paint will work on this tarp pretty well. Now all i have to do is find bigger cans and of the colors i want.
