How Does Finalsan Work?

 

Herbicidal soaps work by penetrating the waxy cuticle of plants, causing the plant to dehydrate and die. The active ingredients accumulate in plants and cause intracellular damage, leading to cell death. Activity is non-selective and will kill plants the soap comes into contact with, but will not translocate to underground portions of the plant or harm the bark of mature, woody plants.  Can be safely sprayed around the base of trees, shrubs, hops, grapes without worry.  

Use on weeds within vegetable and flower gardens, landscaped areas, lawns (for spot treatment only), in the vicinity of small fruits and fruit trees, around and on buildings, sidewalks, fences, bark mulch, driveways, patios and gravel.  Use on moss and algae, around and on buildings, roofs, decks, sidewalks, fences, bark mulch, driveways, patios and gravel. Finalsan can even be used in cool weather. Areas can be planted five days after treatment.

Finalsan reduces tree toxicity risks and leaves no harmful residue in the soil. It won’t stain bricks, concrete or asphalt and people and pets can re-enter areas once spray dries.

    Helped to improve combustion in 12 year old Mercruiser 3.0L engine
    Color: Blue, Number of Items: 1
    I used the whole bottle in 1/2 tank of questionable gasoline from used boat from dealership, with no idea what mixture of gas water and particulates was in the gas tank in this 12 year old boat. The dealer started up the boat, and it was taking a minute to get the idle going. He mentioned that the gas was a few months old, but I am guessing that is was more like 6 months old. This is the TKS engine, self priming. I think some water / condensate was in the tank. Before taking out to first trip, I added bottle and 5 gallons fresh gas. That trip to the lake, I still has some issues getting it to start easily. Ran OK, not great that day, went home, changed cap and rotor and wires. Next trip, 1 week later, the 3.0L started great, ran great, I am not sure if it took some hours to fully mix and interact with the old gas, neutralize the water, and perform it's reactions, before it made existing gas more combustible, but that is what it seemed like to me. ***UPDATE**** - I had strange fuel issues the next season after using this product. I had to replace the fuel pump and many other fuel delivery components including the carburetor. Not sure if this contributed to the fuel system failing, the long term effects outweigh the short term gains.

    Works. . .
    Color: Blue, Number of Items: 1
    Left 10% ethanol gas in my 3500 watt inverter and forgot about it. After I got it started, it was suging and alsmost unusable even with fresh gas. Drained all the gas and used a measuring cup to get the fuel/additive ratio right and let the generator run wiuth a 1000 watt work light. AFter about 15 minutes, the surging stopped and engine smoothed out. Happened faster than I expected. Taught me a lesson about gas decomposition. Promised the genny I learned a lesson to use stabilizer. Easier than doing a carb rebuild.
