I think it was Melodica-Me who said in an earlier thread that silicone might damage the gasket. I had been using it on my Suzuki Bass-24, which leaks like a sieve. Beeswax sounds like a promising possibility, especially if it’s something used by accordion users. I’ll try this: I Googled “gasket in a can” to see what came up, which is this kind of product: for auto-motive applications, but it is silicone based.
