Hey JK,
The Animal comes polished because it was too much in it's dull state to be used on the "THS". Track states this on their flyer that they had to tame it with clean and sheen so it could be more useable for all around conditions. All you have to do is take it down to the grit you desire to match the amount of oil that you encounter. The covers from Track are very versatile and can be adjusted accordingly...check out Excaliber's thread on his 2nd Animal sanded, sounds very promising for heavy oil. Sorry, haven't drilled or seen a KI in action, not very popular in my area. Hope this helps some...
