Everything depends on the client's budget. We can use power tools for surface preparation for a smaller budget or abrasive blasting for a bigger budget.

If the tank is small and the coating close to the end of its life span, reblast and recoat. Do you mean preventive or corrective? Damages in coating only or down to bare steel? If the coating is old and you encounter partial breakdown, what happens to the remaining, presently intact coatings? To touch up local damages may result in weak points, especially of boundaries.
