What is the difference between the three surface finishes?
Primer is an unpainted surface that will need painting prior to install. It is unadvised to install a primer unit as there are no UV stabilizers to protect it from sunlight exposure. Satin Black is a matte black finish that is dull in appearance similar to what you would see if you black Plastidip something. The textured finish is a road guard type finish we put on the extensions. It is black in color, and has a rough textured to it.
