Can be applied using both rotary and eccentric polishing machines. Apply 5 pea-sized drops to a suitable polishing pad (Heavy Cut Pad, Lambswool Pad short or Twisted Wool Pad) and work crosswise. Spread the product evenly over the surface at low speed. Then polish with a rotary machine at max. 1000 rpm (eccentric machine on the highest setting). Remove any remaining polish with a Polish & Sealing Towel. On dark surfaces, polishing marks can be removed with Gelcoat Micro Cut. We recommend sealing after polishing with Gelcoat Finish, Marine Protective Sealant or Ceramic Boat Hull to close the pores of the surface.
