    The Difference between Gelcoat and Resin

    A gelcoat would normally have about 3 times more thixotrope than a typical laminating resin. This increase in thixotropy means that the gelcoat can be applied to the recommended thickness of 0.4 - 0.6 mm in a single continuous film without drainage on vertical or inclined surfaces. The laminating resin could not do this, and obviously the gel coat would not wet out glass reinforcements as a laminating resin does.
