This one is pretty quick. I went to get the gasket adhesive everyone says you need. I want to be sure, do I want GASKET SEALENT or GASKET MAKER. I assume it's sealant. If so, which one. Permatex makes like FOUR different kinds. One had a nuimber two on the tube, one had a one, etc. Can any valve adjustment experts tell me which kind in particular I need?
