Instructions
Wash and dry the horse trailer.
Remove rust spots with sandpaper. Rust in easy-to-access places can be sanded away with automotive sandpaper. Sand in a circular motion until all of the rusted metal is gone and only metal remains. Try your best not to sand any areas that are not rusted. Sanding removes layers of metal.
Apply a chemical rust remover to deeply rusted areas, holes and other hard-to-sand spots on your trailer. Spray or paint the rust remover on according to the manufacturer's instructions. Allow it time to chemically remove the rust (anywhere from two minutes to 24 hours, depending on the product). Then rinse, wash or wipe the chemical remover away.
Coat the exposed steel parts of your trailer. The only way to prevent rust from forming is to protect the steel from exposure to oxygen and moisture. Spray or paint on a rust remover or apply a coat of steel primer followed by two coats of paint approved for outdoor use.
