blanking gate valves
I am in the process of restoration. My boat is on a "semi dry dock", that is on a very high tide it floats in about 1 foot of river water. I noticed that has two old gate valves which are leaking. Eventually I think will glass over but in the meantime is it enough to remove them from the thru hull then to screw a female blanking plug onto the thru hull and use thread sealant? Would i have any problems matching threads?
