We also provide dock sealing with Wood RX specially made for the South Florida environment that can only be bought by a marine contractor. Test studies showed that Wood RX would stand up to Florida's excess heat and humidity, driving rains, intense sun and constant mold and mildew growth. We challenged the best test of endurance. We not only beat them, but we also surpassed their effectiveness by as much as 3 to 5 times in every category from appearance to protective longevity for marine construction.
