Awlgrip and Awlcraft 2000 are two different types of urethane topcoats manufactured by Awlgrip. Each one has its own advantages and disadvantages and when trying to decide which to apply, it is important to know the differences between them.
Awlgrip is based on a polyester urethane resin and Awlcraft 2000 is based on an Acrylic Urethane resin. At the surface they seem very similar, but at the molecular level they are vastly different. Polyester molecules are much smaller than acrylic molecules. This means that at any given volume, there can be more polyester molecules than acrylic and this allows polyester films to be more dense and tough. Awlgrip has more abrasion and chemical resistance than Awlcraft and is usually more rigid.
Awlcraft, on the other hand is not without its own advantages. It is generally easier to apply. The larger molecules and less dense film of the acrylic allows for faster drying and therefore less dust entrapment in the finish. Both urethane topcoats will resist staining and provide a long lasting gloss. It is best to consider cure times, reparability, application methods, chemical resistance, as well as abrasion resistance when deciding which topcoat to choose.
Which is more suited for buffing?
Both Awlgrip and Awlcraft 2000 urethane topcoats have a protective resin layer. This layer is the first line of defense against UV light and abrasive damage. Underneath this resin is a layer of rich pigment particles that give the paint its bright shine and color. Awlgrip has a thicker protective resin layer and when the polyester is scratched, it is necessary to cut deeply into the resin to repair it. Buffing the surface leaves the pigment exposed and compromises the performance of the paint in the long run.
Awlcraft has a softer finish, due to the less dense molecular structure, and thus has a lower melting point. When this acrylic urethane is buffed, the resin is able to flow together and does not require cutting the surface as deeply. So, Awlcraft 2000 is more suited for buffing and Awlgrip will require a Fairing Compound.
