Abstract
A method to prevent gelation of an uncured gelcoat composition during storage is described. The method includes applying a gelation inhibitor to the surface of a gelcoat composition in the container to prevent premature gelation. The gelation inhibitor additionally prevents the formation of a crust on the inner surface of storage container lids.
