I used to be a marine repair "pro". Couple years ago I did a port replacement on a boat that had ports mounted similarly to C&C's. The first thing I did was to remove ALL the old sealant and properly prep the adhering surface. IMHO, and from years of marine repair, proper preparation is 80-90% of a quality job.
