Abstract

A fast hardening clear coating composition for repairing a clearcoat/colorcoat finish of a vehicle, which composition is capable of being wet sanded, buffed or polished to a high gloss finish on the same day of application, comprising a film forming binder and an organic liquid carrier, where the binder contains a hydroxyl component comprising a hydroxyl-containing acrylic polymer and a hydroxyl-terminated polyester oligomer, and an organic polyisocyanate crosslinking component, at least portion of which comprises a trimer of isophorone diisocyanate, where the composition further contains, as a combined curing catalyst, at least one dialkyl tin aliphatic carboxylate, at least one tertiary aliphatic mono or diamine, and at least one aliphatic carboxylic acid, in an effective amount such that the clear coating composition on curing at ambient temperatures is in a water spot free and sufficiently hard state for sanding or buffing within about 4 hours after application or on cool down when baked under normal conditions.
