A semi-permanent coating which is made of acrylic or polymer, first introduced by Lacroe and made popular by brands such as Supagard and Diamondbrite. These types of coatings typically lasted 3-5 years, and much longer when maintained with aftercare products. 

Within the industry, the word 'sealant' is used rather loosely, but typically, when it comes to retail products, it means a synthetic wax or product that contains synthetic waxes or polymers. However, these products don't tend to function much differently to natural waxes, so for our purposes, we define them as waxes, and reserve the word 'sealant' for semi-permanent coatings which last years rather than months.
