Re: Best cork carb float coating

[jim-moffatt]

I used new cork stoppers from
https://www.onlinesciencemall.com/
They are not wine corks, they are made for sealing chemical flasks.
I bought them oversize and sanded them down to the desired shape. I have no experience with wine bottle corks.

The site sells 3 grades of cork and I bought the best grade.

Again 3 months and no deterioration.
