I have used three different types of JB Weld. The regular, the Kwik and the JB Stick. I am completely satisfied with all three. I used to use it on small engines. 100% success rate on repairing blocks after dumb folks over worked their mowers, etc. and broke connecting rods. Actually had to use it on an old 302 in a TA-75 tow tractor years ago...........DOC remember the Garwood? Dave Shaver
