Pin-Tite is essentially the stuff they use for anti-freeze in cars. It makes the wood fibers swell which in the short-term may create more friction for the tuning pin, but it does not add any mass or density to the wood. It just puffs the wood up. Which weakens the wood structure in the long-term, because the wood density is actually reduced... CA (CyanoAcrylate) glue seeps into the wood and hardens there - adding mass and density to the wood, which strengthens it.
