Things to Consider When Buying a Boat Wax
Boat Wax or Boat Polish?
The main difference lies in the material a product is made of. A boat wax has a wax base which is typically carnauba, while a boat polish is made of different chemicals and polymer technology.
Boat wax is best used on new boats with light oxidation; it can be applied by hands or boat buffers. Anglers can also use boat polishes on new boats.
You can also use it on old ones, but the oxidation must be cleaned and removed first. Boat polish can be applied by hand or an electric polishing machine.
You should also know the type of boat you own before deciding what to buy. Not all waxes are compatible with all boat materials.
The typical components of boats are gel coats and fiberglass, so you should be aware of the products that are compatible with these materials.
