Polyurethane coating compositions are disclosed that include an isocyanate-reactive component that includes a polycyclic polyether polyol that is the reaction product of a reaction mixture that includes a polycyclic polyol starter, and an alkylene oxide, as well as an isocyanate-functional component that includes a non-aromatic polyisocyanate. The polyurethane coating compositions may be particularly useful as a gel coat in the manufacture of glass fiber reinforced plastics.
