a good way to check if you need to clay is put a plastic baggie on your fingertips and gently rub the paint...this helps emphasize your tactile response. if it is gritty or grabby, you have contaminants on the paint, use clay...try the same spot after claying and it will be dead smooth.
you can also get a product called ironx if youre worried about rail dust, or the clay marring your paint. it does a great job of cleaning the contaminants and doesnt require a polishing afterwards.
Rail dust is what vehicles with 0 miles on the odo can still have. Regardless of whether or not they have been driven. I don't have much to add other than I agree with what's been posted.
New vehicle's paint is baked, NO additional cure time needed.
Mechanically clean the paint = clay the paint, it can still have contaminants.
Chemically clean the paint = optional, but you'd be surprised what isn't removed with clay. I use Optimum Poli-seal, I find that I can completely clean and decontaminate my car and Poliseal on a white Microfiber will still look brown/black when I am done with just the paint.
