For anybody to help you more information is required.
1. Where geographically is this project located?
2. Is there more than one above ground portion?
3. How long is each above ground portion?
4. Why do you want to paint over a "coal tar epoxy coating" that will not last?
5. Have you considered any other options (say Cladding as is used with Insulation)?
Sometimes its possible to do all the right things and still get bad results
