I like hammerite.. I think it even has some prevention of galvanic corrosion
even if it gets damaged a bit. There are also paintable zinc-based layers
specifically to extent the life of steel. I guess the impossible thing tio
grant is totally maintenance free seals, but many methods likely don't need
much more than one reworking per decade. I just wouldn't trust my estimate on
milage in sea spray.
