The sensors for the Seelevel II are water resistant, but not water proof. There is a rubberized coating spray that you can spray on top of the senders to protect them from the weather. The part number for this rubberized spray is 03584. On installations where the holding tank is exposed to under chassis road spray and flying rocks etc. we recommend the use of an auto body undercoat, which is easily purchased in auto parts stores. This tar based material clings well to the senders and protects from water and debris. One material in particular is 3M Professional Grade Rubberized Undercoating, product code 03584. Another product that works well is a Dominion Sure Seal rubberized undercoating such as Gravel Guard Rocker Guard Coating. After the system is completed and tested apply the undercoat over the complete board using 2 coats. Do not use lacquer, enamel paint, or plastic paint for auto bumpers as these contain chemicals that will dissolve the conformal coating on the board and cause malfunctions.
