The Red Roo SP7015TRX is prepared with garnet blasting, a highly effective and environmentally responsible abrasive process used to remove heavy rust, mill scale, and old coatings before repainting. Garnet’s natural hardness and sharp angular profile provide fast, clean cutting with minimal dust, leaving a consistent surface profile that helps new paint systems bond strongly and last longer. This process is ideal for refurbishing hardworking equipment exposed to tough Australian conditions.

The equipment is first primed with a premium epoxy-urethane blend to provide outstanding corrosion protection and to help seal minor surface imperfections in the metal. Following priming, a premium two-pack polyurethane topcoat is applied. This advanced coating system combines a polyurethane resin (Part A) with a chemical hardener/catalyst  (Part B). Once cured, the coating forms an exceptionally durable finish that delivers excellent resistance to abrasion, chemicals, weathering, and UV exposure while maintaining a high-gloss appearance.
