Yesterday I received leather conditioner and a grey foam hex pad applicator. I applied the conditioner to my steering wheel as well as my aftermarket armrest. The leather conditioner applies very thin and easy and appears to self-level after a few minutes. It is a liquid so I applied some to the foam applicator and worked it into and around the steering wheel. It doesn't have a strong scent, it spreads thin, and most importantly after about 30 seconds it is completely dry to the touch. No greasy feel. Works great.
Below is a picture to show how dark and rich it made the steering wheel look. Total time spent was about 5 minutes and again, even though it looks deep and shiny, there is still no greasy film left behind.
