Yes, I tried it and won't continue. It seemed to work for the time it was on (which is until the first or second good rain). I plugged-up my good backpack sprayer with the crud which apparently includes an egg product. Maybe that is where the smell comes from. It was very difficult to mix (comes in two parts) and to keep it mixed so it would not come out of suspension while spraying. This problem may have been my fault, but I won't try to go that route again. I was trying to protect my red oak seedlings, and the following year I just tied white paper popcorn sacks on the terminal (main) buds during the winter. Most of these sacks stayed on through rain, snow, and wind - I took them off when the new bud-growth started. This solved the problem of the deer browsing on the buds before they opened, but then the deer switched to eat the new growth throughout the summer. This year I didn't do anything, and so far the deer damage has been minimal.
