● Select epoxy zinc-rich primer or acrylic acid top coat with a color the same as
the surface coating color of the equipment.

using an aerosol spray, brush, or paint spray gun until all damage traces are
invisible.

undamaged areas and those with
dierent colors as the damaged area from
being contaminated during repainting, cover such areas using white paper and
adhesive tape before repairing paint.
