Diesel tank lid seals
I've just started opening my keel diesel tanks to empty, clean and debug. Steel boat, steel keel, steel tanklids. Having anticipated finding nitrile joints under the lids, I'm instead faced with a load of sealing compound of some sort which is making the lids a right bu**er to prise off. The sealant is set into a soft rubbery consistency and is the colour of red Hermetite. Anyone know what it might be? It's proving incredibly difficult to clean it all off in order to use a gasket next time so may have to resort to using the same stuff again, if someone can identify it. Thanks for any suggestions.
