Copper, brass, lead etc.

Generally these metals are regarded as corrosion resistant and normally do not need coating for protection.

Copper, brass and lead are sometimes painted for decorative purposes as part of a general painting scheme. Normally blast cleaning with non-metallic abrasives or mechanical abrading and degreasing are required. As they are corrosion-resistant primers and undercoats are not normally recommended. Two coats of the finishing material should be applied direct the first coat thinned 10% to improve adhesion.
