sgcampbell Report post Posted May 25, 2015 I just replaced my original Xantrex inverter with a Magnum 2012 PSW invereter. To do this I had to cut away the rubberized sealant around the wires coming in to the compartment where my inverter is located. Now that it is installed, I need to reseal around the wires to prevent water entering the compartment. I have a 2004 Newmar Mountain Aire Diesel. Does anyone know the brand of rubberized sealant used by Newmar to seal wires entering compartments? It was brushed on originally. Share this post Link to post Share on other sites

hermanmullins Report post Posted May 26, 2015 dd69, Do you know how well this product holds up to out side exposure? I have some thing penetrating the exterior walls of my Garage that I would like to seal really well. Herman Share this post Link to post Share on other sites
desertdeals69 Report post Posted May 26, 2015 I've used it for several different apps. Holds up well. It is sometimes referred to as liquid electrical tape. You also might look at marine silicone which is approved for underwater application. Share this post Link to post Share on other sites
kaypsmith Report post Posted May 26, 2015 Herman, if it will be exposed to the outside, black rtv sealant, can be obtained at most autopart stores will work very well. Use black, as it is the only color that is not affected by ultraviolent rays. Bet you have never seen a power company wire outside any other color than black, this is the reason.
