This is a multi-step process; 'sounds like you may not have paid attention
the individual steps properly.
1. Coating selection -- I this a moist or corrosive environment? Is
abrasion a problem? Do you want a long-life system, or simply a cosmetic
2. Proper surface preparation is the key. Without it, everything else
will be less-than satisfactory. In your case, I think an SSPC-6 would be
3. Assuming you have opted for long-term quality instead of something
temporary, I have assumed good surface preparation (see above), followed by
a multi-coat system. I have also assumed a cyclical "caustic" situation,
followed by periods of "acid" saturation.
I have also assumed you want something with a certain visual quality. This
calls for a relatively impervious base with a "finer" top coat.
4. With the requirements outlined, it would seem that the most appropriate
coating system would consist of a base coat of tar, followed by a topcoat
of feathers. And, incorporating mobility considerations, I would recommend
provisions for being transported "out of town" -- "on a rail" might be
