d. Maintenance of Painted Surfaces
The refrigeration unit is protected by a special paint system against the corrosive
atmosphere in which it normally operates. However, should the paint system be
damaged, the base metal can corrode. In order to protect the refrigeration unit from the
highly corrosive sea atmosphere or if the protective paint system is scratched or
damaged, clean area to bare metal using a wire brush, emery paper, or equivalent
cleaning method. Immediately following cleaning, spray or brush on zinc-rich primer.
After the primer has dried, spray or brush on finish coat of paint to match original unit
color.
