Apply the gel to the knife. Make sure to use rubber gloves; this stuff will burn you. Cover the entire knife, and let it sit for about 30 or so minutes.
After waiting 30 minutes, I then used an old credit card (don't use a current one) and scraped the coating off the blade. It came off very easily with minimal pressure. Afterwards, rinse the knife and apply some oil to prevent rusting.
All in all, I'm very happy with the upgrades. The BK2 is a lot of knife for the money and it looks great when dressed up.
