Most likely it will still cure but, at the expense of your paint. Painters call it "solvent pop". As the liquid chemicals continue to cure, it will blister the paint to let the fumes out. Id say give it the full cure time.
well I just went ahead and painted over it anyway, it's the bottom of the boat so it does not have to be perfect by any standards. Better than 100% white patch marks which I don't like.
