All AcuSpike Spike Trainer painted surfaces are powdercoated with a high quality 3 mil. powdercoat. This type of finish is the premier standard for creating the best aesthetic, durability, and longevity. Powdercoating is applied electrostatically and then cured under heat to create a hard finish that is tougher than conventional paint. The base frame, which is expected to be handled for rolling the unit, is textured during the powdercoat process for a rippled finish, while the rail and upper post have a glossy finish.
