A common problem with chrome plating is chrome burn caused by high current densities. Chrome burn along with lap marks, or smudgy wheel work, can be eliminated with special dry coloring compounds called chrome rouges.
HR (86/80 Cotton Cloth) loose full disk buff is generally recommended for buffing out chrome burn and BR (60/60 Cotton Cloth) buffs are recommended for clean up and coloring operations.
The following chrome buffing compounds are excellent for any metal or plastic. Chrome is very hard and compounds designed to buff chrome, but not break through a thin chrome plate will color any softer material.
