Ah yes the Viper! :xyxthumbs What a raw, poweful yet beautiful car! Your Viper in these pics looks super cool I must say. The NXT looks great here as a last step product. It almost has a Souveran look to it. Very, very wet!
NXT is short for NXT Tech Wax, a new synthetic paint protectant by Meguiar's. It is a part of a new line of products called NXT Generation.
It is just now coming out onto the market. It is for cars whose finish is in new or excellent condition, or have been previously prepped including removing bonded contaminants using a clay bar, followed by paint cleaning using a dedicated paint cleaner, and or cleaner/polish.
I have achieved my best results after first prepping the finish, (like any wax), only from my experience, it leaves a very clear, smooth, high gloss finish with an almost wet-look.
There will be a Viper Detail Day at Meguiar's on April 10th if your interested and in the area.
