Priming

• Paint will not bond to Ospho-treated metal unless the surface is coated with a bonding primer. Unfortunately, water-based latex and acrylic primers do not adhere well to metal and will ultimately peel away. An oil-based primer won't stick well to bare, untreated metal, because the surface is too slick; however, once the metal is treated with Ospho, oil-base primer will adhere. Although Ospho works to alter or eliminate rust, it does not provide long-term rust-inhibiting protection. To prevent a recurrence, choose a rust-inhibiting oil-based primer. Red oxide primer will provide good adhesion and strong protection against future oxidation.
  
  

Oil-based Enamel

• Once the metal is primed, apply paint. An oil-based enamel will provide an attractive, glossy finish able to hold up to considerable duress. Choose this finish for nearly any metallic surface in and around the home.
  
  

Lacquer

• Lacquer paint is a thin finish that dries flawlessly when properly applied. Typically used on cars, trailers and sport utility vehicles, this type of paint can be difficult to apply. Unless you're experienced using lacquer paint, consider hiring a professional to paint your vehicle or trailer.
  
  

Epoxy

• Epoxy paint is a two-part finish well suited for interior metallic items. The paint comes in two components that remain liquefied until mixed. Once they are mixed, the components harden into a durable, glossy finish. Don't use epoxy on exterior metal, or UV rays will cause it to fade.
  
  

Marine Enamel

• Marine enamel is specifically formulated for metallic watercraft. Use this type of paint on boats, boat trailers, metallic fishing lures and any other items consistently exposed to fresh and salt water.
