I'll check into 3M Cavity Wax, sounds more like exactly the product to seal things.
"Lanolin (from Latin lāna 'wool', and oleum 'oil'), also called wool fat, wool yolk, wool wax, sheep grease, sheep yolk, or wool grease, is a wax secreted by the sebaceous glands of wool-bearing animals.I don't know anything about Krown.
There is NO SIMILARITY between FluidFilm and 3m Cavity Wax. FluidFild is a lanolin (from sheep) based oil. Exposed to water, it will wear off is a couple of years. The 3M stuff is a "wax". Like stays longer than FluidFilm.
