I am sure there are many great products to use. I have been using 303 Aerospace Protectant since I got my 2000 Acura 3.2TL new. I made a special trip to get a big bottle at West Marine the second day after we got the 2007 G1 Ridgeline. I treated all surfaces of the truck that I could use it on. It provides exceptional UV protection and soil dust/stain /water repellant. It's for finished leather so you can use it on leather seats and steering wheel without that slick feeling.
I found out about it when I was on the old AOL Acura TL forum have used ever since. Can be purchased from other retailers like Autogeek
Make sure it's the Aerospace Protectant because 303 has a line of products.
