Grenadier Bumper / Paint Detailing?

[BiggerWhiskey]

Random question - but I've seen photos of Grenadier bumpers that look detailed and much cleaner / darker than the more faded gray look when they arrive and have been sitting outside. What detailing products are people using to get their bumpers / cars looking this clean...photos attached below of what I'm talking about....Thanks
