Thanks for all of your responses and feedback! To be clear this is far from finished and luckily I bought way too much cork bark. Here’s an update on my progress.
I think I will move forward with the great stuff and start with small amounts. I would hate for it to rip off the silicone so thanks for the caution. I think my can does have the straw with the cap so hopefully I can get a few uses out of it.
Unfortunately I work all weekend but if I have time I might get back to it late tonight. I’ll keep y’all posted with updates as it progresses and thanks again!
