Slowed but didn't stop the water drain from the meat grinder. Water always finds its way through the smallest cracks and channels. You can put 5 pounds of this stuff on anything you're renovating, but be aware it's temporary and expect some level of failure. To be honest, Putty can't think for himself. It will not automatically fix a leak just because you followed the "T" instructions. If it slows the leak to a trickle so your catch bucket doesn't fill up as quickly, you win.
