Dear David, I can suggest to use the alcohol & Glycerin TPT. Just use about 2 drops per pin. The liquid will run along the pins and they will never crack again. This solution has worked for me and seems to be permanent(10 years so far). You will save a fair amount of time and trouble. Plus I don't think 2 drops will be enough to ruin the block IMOHO.
