I would say it depends on the condition of the car you are working on. NXT scratch hiding abilities are not that great. I would say for the same work that goes into applying NXT doing the detail I just did washings aside is just as much labor.
links to products are in that thread
The only product I have to "apply" was prime strong which is a much better paint cleaner and swirl/scratch fixer than NXT. Also, mixed in is a light wax booster and sealant. Sure the price point is higher but why not spend a little more for a much better product with loads more of durability. Once you apply the primestrong, just spray some Opti-seal on there or Acrylic Jett Trigger wipe off, and then spray a coat of Duragloss Aquawax and wipe off.
This combo would last at least 3-5x times longer than NXT and shine would have a lot more depth.
Some might argue product are more expensive. Well lets take Opti-seal, at 25 dollars a dime size application will do one or two panels. So in one bottle you get about 20-40 car applications. When you break it down like that it is a bargain buy. Also, Optiseal is a wipe on walk away product and Aquawax being a spray on wipe off product.
Plus, I don't understand the available everywhere issue. Just order on Monday and you will have it for the weekend to clean up your car.
I didn't mean for this to come off harsh or anything. I just want people to know of other options that are better.
