          Spraying over the top of installed 4x4 fence posts caused a huge mess
          Used this product from a bottle before and have no complaints about it. Tried spray version of it and regretting a lot. I was trying to spray the top of 4x4 fence posts cut to the length after post installation. The slightest touch creates a huge stream of solution spraying around and spilling over the post creating a disgusting dark drips If I knew I would buy a solution in a bottle and used sponge like I did before with much better results. This probably would work if you need to spray-pain the whole section of a fence, but I doubt it is necessary. Disappointed
          Response from GreenproOct 6, 2020
          Sorry to hear the spray application was not what you were expecting. Sounds like the brush method for the small 4x4 top of fence would work best. Please give us you mailing address and I can send you a free quart bottle of the wood preservative.
            This treatment is strong
            Make sure you wear a respirator and gloves when you spray on this treatment as it has a very strong smell. I used this treatment on some lumber I used to create a frame that went in my garden. I live in the mountains and termites are rampant. So far no signs of termite infestation
