Yup sure can but wouldn't advise it. ALL bondo products use Talc as a filler and talc absorbs water and if the gelcoat gets a chip and then water gets in the entire patched area will be breeched and become a problem. I guess you could use it for a small patch in an above waterline area but still I'd rather use a product that was designed for marine use like the 3M Marine Fillers.
