This is the sealant I used in the RV solar install video to keep the critters out. I placed a little bit of this around the 10 gauge wires both on the inside and outside of the drilled holes to insure that nothing would getting through there. Neither place I placed this silicon sealant should encounter heavy amounts of moisture, but it should keep the wires sealed tightly.
It did not take long at all for the silicon to harden in place to start protecting that area.
