Por15 rust inhibitor.
best bilge paint from the local Lowes hardware store. This stuff does everything I need it to do except apply itself. And it is dry in about an hour. I like the fact that it really doesn't need any sanding, I do anyway, and it is mold and mildew resistant.
silicone dielectric grease to keep corrosion down.
The battery will now reside in a plastic battery box with built-in vents. The cables from the battery to the starter are now about a foot long. The battery end of the cables and the battery terminals also received a coat of silicone grease. There is still a long negative cable that runs from the starting battery to the house bank and the echo charger which keeps it topped off is also run from the house bank. I did have to add a side support to keep the box and battery from sliding around on the new compartment since it didn't quite fit snugly.
