Since the kayak was fiberglassed with its final fill coat has been sitting in the overhead for many months, getting the aersol mist from Corrosion block, WD40, Windex, numerous spray paints, what should I do first 1) sand then wipe with acetone, then put on one last coat of epoxy OR 2) wipe with acetone, sand, then put on another epoxy coat? I am keeping the whole boat bright. Thanks - Chris
