Yep. Very very sticky. Oily.
Bummer. I've been wanting to order some from yakima, but that doesn't sound too fun. I am a rinse only guy when it comes to my kettle and chiller. Once or twice a year I'll scrub with barkeepers friend.
It is not hard to get clean the kettle. It does tend to clog up my scrub sponge though. It feels like pitch, but cleans much easier.
The real value is that it doesn't add the volume of hop material that pellets do. I want my IPAs maxed out on IBUs and flavor/aroma additions, and that takes a lot of hops (my latest 5 gallon IPA batch took 13 oz. of hops in addition to the hop shot for bittering).
