We bought an old bottle of Moguloid block seal (to fix holes in the cylinder head). But the contents were no longer liquid and was solidified - like a rock. The shop owner ended up giving it us for free because of this and told us to hit it and break it to powder - I assume the next step is to put it in water so it liquifies again?

Anyway, will this work? Do we add water to it? How much water?


  • I don't think it can be re-liquified again once it has set. – Rory Alsop Apr 27 at 8:57
