The subject invention provides a resin component, a sprayable elastomer composition that includes an isocyanate component and the resin component, and a method of making a composite structure. The resin component is reactive with the isocyanate component and includes a first polyol and a second polyol that is different from the first polyol. The resin component further includes a moisture scavenger and an anti-settling agent to prevent the moisture scavenger from settling out of the resin component. For the method, a first layer is applied to a mold cavity. The first layer is a show surface of the composite structure. The sprayable elastomer composition is sprayed on the first layer to form a support layer. The composite structure is then cured in the mold cavity. After curing, the composite structure is demolded from the mold cavity.
