I have seen several threads on this informative hub regarding Swamp Cooler Pan Repair - Issue: As the swamp cooler ages, the pan that holds the water may deteriorate, become rusty and develop small holes that can leak.
Unfortunately - it is very difficult and can be quite expensive to repair these pans - until now. We are the sole distributor for a new Liquid Rubber product that can be applied with reinforcement cloth as a strength member. Once this water based UV Stable product dries and vulcanizes - your pan is permanently repaired - and rust is also stopped in its tracks.
