Abstract
Watercraft can be manufactured from a blush-resistant gel coat composition which in its cured state resists long-term water immersion. The cured gel coat composition forms an outer opaque layer in a multilayer (e.g., two-layer) laminate, and is made from an unsaturated polyester resin, reactive diluent, and sufficient pigment to provide an opaque cured coating. The composition is sufficiently free of extender filler so that the cured coating will not exhibit blushing after 6 hours immersion in 66° C. water.
