You can put seafoam in your engine and the gaskets won’t dry up. ---

RTV on a flat surface rubber gasket is going to be prone to leaking. Should only be used in sharp corners as suggested. On flat gasket and orings, use either Hylomar or Curil-T non hardening sealants to actually bond the gasket to the parts to be sealed. Most agressive cleaners cause rubber to swell. Viton is immune. Use warm water and dish detergent to properly clean a rubber gasket that must be reused. Rinse and pat dry(NEVER pull a thing rubber gasket/oring through a towel to dry…you will stretch it). ---
