At the beginning of the year I bought a 1981 C&C32. I really enjoy this sailboat but there are several repair that must be made this winter. My priority is to fix all water leaks and for starter I rebed the bow hatch and remooved the old 1/2 inch lexan lens from the Atkins & Hoyle cast alluminum frame and I am ready to replace it with new one. The old lens was probably replaced by the previous boat owner and sealed with marine silicon that did not do the job. Does anybody know what is the appropriate selant for this project?
