Up until two years ago I only ever used Copperslip.
You highlighted numerous issues you were having with head gaskets seeping internally - and reported using spay on Hylomar to cure at that time.
I spoke to Terry Griffin who had mentioned using the copper silicone and asked him why? He told me that he had used it as a preventative measure for some time.
Steve Jones later told me that it had originally been developed for Fiat (I think that is correct) with the intention of it replacing copper type gaskets all together. This did not transpire but the product was made and can be used as described above.
I have used it on around 30 engines since then.
I have no personal experience of the gaskets weeping but your reports as to the failings of the new gaskets were vociferous enough to convince me that bad times were coming. I had no reason to doubt you, so use it in the spirit of a “belts and braces” approach - which sits happily with my general outlook on such things.
