A friend tried something last summer on his new wheel barrow that really works. Buy a can or two of spray on bed liner at an auto parts store or Walmart. Sand the paint lightly and degrease the metal and then spray the inside and upper lip following the directions on the can. You can spray the outside too if you want to, just mask off the bolts so you can take it apart some day if you have to. He just moved 15 tons of gravel and it never even scratched the liner! It seems like a great way to preserve something you need to use a couple of times a year. I’m wondering what else that trick could be used on? Flower boxes? Maybe tool handles? Any other ideas gang?
