I greased the Kubota with my new DeWalt 20 volt grease gun, but I am torn between using black grease or red grease. The black goes better with the Orange color of the tractor, and the red grease clashes with the orange of the tractor. I am also considering changing to blue grease. What color grease do you prefer? Also, do you wipe up the excess grease that spews out when you don't use a tight-fitting adapter on the nipples? I always wipe all around the nipples.
