Where can I get Screen Boss screen sealang calk?

[newbiescreenprinter]

I used Screen Boss screen sealant calk around the sides of my screens. It is time to redo some screens and I have some new screens and the old place that I ordered from Screenprintingsuperstore.com does not carry it any more. And I think the website for screen boss is offline. Did he go out of business? I know I had trouble with the unopened tubes of calk hardening inside the tube and not being able to use them. I wonder if that killed his business.

Is there some other place I can get it? I don't see it on google anywhere.
Is there another type of calk I can use from a hardware store? Maybe a good silicone calk made for outdoor use?

I like using a product like this rather than tape because the tape collects ink along the sides.
What do you recommend?
Thanks
