Preparing your surface for paint is essential with marine applications. For your first coat, primer paint should be applied to any surface that you are painting. A primer will provide you surface with the right adhesion for your main paint base. A primer will also give your surface an extra layer of protection from the elements. This extra layer of protection will allow your paint to last longer on your surface. Wholesale Marine carries Pettit primers that will work with metal, wood, or fiberglass. These primers will start your painting project off right and make the hard work that you put in last.
