Many boats that are made of fiberglass have a coat of paint on them. Generally speaking the more expensive the boat, the more pure colored fiberglass you will see. Why am I mentioning this? Because the heavy duty oxidation remover in this kit is designed for rock hard fiberglass, and not for paint. It is a bit aggressive for paint unless it is super oxidized, and needs a layer removed. This level of scrub is not designed to give you polish or gloss, but rather to remove the surface oxidation. So that is why they provide three different formulas. This kit includes: Meguiar's heavy duty oxidation remover (M4916), boat/RV polish (M4516) and gloss enhancer, boat/RV pure wax (M5616), soft foam applicator pads - 3PK (X3070), microfiber towels - 3PK (X2020), mirror glaze apron.
