Should I dip them in wax to preserve them? (20+ years potentially)

For context: The Capitan Flash bottle in the middle was a 32yo bottle of rum my dad had saved for his first child’s wedding, which ended up being me… but the cheap metal cap most definitely didn’t help it age gracefully, as it lost all of its colour in that time and smelled/tasted like pure formaldehyde (never had a worse hangover in my life)…

The Bourgogne and Bumbu are my attempt to keep the tradition going, but with higher end, corked alcohols as opposed to the cheap bottle that was meant to be enjoyed sooner than later. It was advised that I buy two bottles in the event of a mishap, so I figured I’d have fun with that and get a nice French wine and a Carribean rum. These bottles will be packaged up and stored in our steamer chest we’ve recently bought, where they’ll remain until I have a child that gets married.

I know the bottles should be stored on their side to prevent the crop from drying out. I know the Bumbu shouldn’t age in the bottle, but the Bourgogne will. I’m just curious if I should remove the plastic/metallic paper coverings over their cork caps and instead dip then in wax, as I’ve heard it was the traditional method to preserve alcohols…

Again, these will be stored away for decades, presumably 20+ years… Should I leave them be, or dip them in wax before packing them away?
