I'm not sure if you are talking about VC17 or VC Offshore, but I sprayed VC Offshore on my J30 for about 5 years. I bought a 1 gallon can and the appropriate thinner. I would then walk around the boat spraying a thin coat. This would usually get me around the boat two times and then I would use up almost all of the rest for another run at the waterline, keel and rudder without stopping in between coats. The little bit left over I would use for touching up where the jackstands and keel blocking were.
