Belzona Facts:

Customer saved several thousand dollars over previous FRP system with easier installation and now can inspect, or if vessel has to be opened, can use a box knife instead of a heat gun or grit blast equipment! Customer had seen Belzona 3411 advertised in Distributor Newsletter and thought it was worth trying this application. The unit was inspected 90 days after the install and it looked as good as it did on day 1.
