Can parts be smooth and others like the bed to be textured?

You vary the texture using the hopper gun controls, air pressure, and using the coarser powdered products on the bedliner for a more textured surface. You would use the finer powder and a finer spray technique on the exterior to make a smoother finish.

You can also topcoat just the areas you want smooth using no powders to get an even smoother end result or add a color top coat.
