Got the silicone/felt samples, thanks!
I’m curious if you happen to know the Shore hardness of the thinner silicone? From this link, it seems like it might be around A20 or A30 or so?
I was thinking of getting some A10 or A20, but yeah, wow, $72 shipped for a 12″x12″ sheet on eBay… ouch.
I’ll start by seeing which reeds are leaking in the first place. Maybe MM’s sheet will be enough for the worst offenders.
