Two-component polyol/polyisocyanate composition especially useful as an abrasion-, heat-, and corrosion-resistant automotive undercoating. The polyol component comprises glycerol, a polypropylene oxide glycol, and a polypropylene oxide triol. The polyisocyanate component comprises MDI (diphenylmethane-4,4'-diisocyanate), plus a poly(oxypropylene) glycol capped with MDI.
