If thats the same dude with the red grinder looks like the anodized paint or w/e it is came off during the soak. Edit: My room fucking reeks of iso! will post pics of finish product.
Sorry, didn't see one specifically like this already posted. I based mine off of Hashmouf's tutorials, so it's very similar to his QWISO methods.
yea i think freezing it would make it even easier than it already is. loosen those thc crystal even further, good call. next time my grinder gets caked out im going to put it in the freezer first.
