3M Perfect-It Gelcoat Light Cutting Polish & Wax is an excellent, one-step, cleaner for dull and marked fibreglass/gelcoat boat surfaces. The blend of the light rubbing compound, combined with polish and waxes are designed to remove light to medium oxidation, chalking, water spots, rust and exhaust stains on fibreglass/gelcoat and marine topside paints.
The end result is a high gloss finish with no need to polish afterwards.
If you need to remove heavier oxidation and scratches try 3M Perfect-It Gelcoat Medium Cutting Compound & Wax or 3M Perfect-It Gelcoat Heavy Cutting Compound.
It is recommended to wash your boat before applying 3M Gelcoat Light Cutting Polish & Wax with 3M Perfect-It Boat Wash.
3M Marine Light Fibreglass Polish and Wax can be applied by hand using a cloth or by machine. Work the restorer into the fibreglass/gelcoat until a satisfactory finish is obtained, being careful not to burn the gelcoat layer if a machine is used.
