7.26 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 refrig-
eration 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.
