OK, a quick report on the 3M tape.
I cleaned my ceramic stones, made sure ty were super dry, and tried the new 3m tape.
Initially it stuck to the stone, then I pressed the stone onto the paddle. Same procedude both sides, both stones. They fell off within 30 min.
So...I said to myself, what am I doing wrong?
I put the stones back in the paddles, sat them on the counter, and weighted them down with my WEPS. (I have the granite base) I left them over night, nad *poof* they hold.

So far going on a week with the paddles on their sides, 2 knives sharpened, and hte stones stick firm.

I think pressure when applying the new tape is a possible fix.

Just my .02

Oh...and no water near them yet...
