Direct to metal (DTM) paint is a protective coating that has been designed specifically for this purpose. As the name implies, this type of coating is applied straight to a metal substrate. Because of the added challenges associated with painting on metal, even advanced technology such as DTM paint may inspire some questions among its users.
