I've searched the archives but have not found any similar issue. My rudder - standard rudder with 82 Catalina 22, has a crack about 1/8 - 1/4 inches wide, that is along the leading edge, above the water line. It is about 1 1/2 feet long, starts above the top pintle and ends past the bottom pintle. Any suggestions or references to repair this crack - it is more than just the finish - it goes into the rudder. Thanks.
