This product differs in that it requires polishing to remove ‘moderate oxidation, stains and scratches’. It can be applied by machine or by hand: we opted for the latter approach, rubbing it into the surface with a cloth, and immediately wiping dry with a dry cloth. After three repetitions it was clear that this would require more elbow grease than the acid-based products, but it did leave behind a nice finish to the gelcoat – although quite a lot of brown staining was still present. Using with a cutting pad on a machine polisher would reduce the effort required, but it still wasn’t as easy to work with as the others.
