What best describes surface prep and touch up in corrosion maintenance?

Explanation:
Surface prep and touch up are the maintenance actions used to maintain and restore the protective coating on metal surfaces. Surface prep means cleaning, degreasing, and sometimes light abrasion so the coating can bond properly. Touch up is applying coating to small damaged areas to quickly reestablish the protective barrier and prevent new corrosion from starting. This isn’t about upgrading an entire system, diagnosing condition, or scheduling full component replacements—those describe broader activities. The best description for these tasks remains maintaining and repairing the coating through surface prep and touch up.
