Another easier to clean up method is using dielectric grease on the seal and all grommets/wires/fuse cap.
Also, tighten the screws evenly and don't overtighten to the point the seal squeezes out. Don't need super tight as the top ebox cover has a narrow extrusion all the way around designed to dig into the gasket to seal. New OEM seal all the way!
That neverwet looks good worth a shot
And I just purchased a nano protection for all electric parts but I got to keep that salt out it was still wet from a few weeks ago don’t know if that was from the lake and the salt deposits were residue from a month ago but that’s got to stop
