I have a black GS (inside & out) - and I love the Meguiar's products. After a good wash - use the quick detail over the exterior and the car shines. The interior detail spray is great to as it leaves the natural matte look on the dash, the wood and radio/nav are clean, there is no greasy feel, and the dust is gone. Great products in my opinion. I admit I still use Armor All for my tires - and for the best shine just spray (mist) it on to the tires and leave it (don't wipe off)....and do the inside wheel well for a good look too.
