I've been using a tank sprayer at work for deer-repel gook, as in Liquid Fence or Deer Out. It clogs fairly quickly but most of the sprayer parts are metal or heavy plastic so I can take it apart and clean it easily. Now I'm on sabbatical and need to get something for home. Anyone have a good quality tank sprayer they can recommend? I'm thinking something maybe 2.5 gallons or 3. I need it also to apply nematodes. At this point I'm watering them in with the watering can and it takes forever . . .
