You can find it at any auto shop. I think I paid around $20 for it. The key is to start off with a "clean" car... so wash it and clay it... and then rewash. Then dry it. Now you are starting off with a clean car. At this point applying the NXT is pretty easy. It goes on easy, and comes off just as easy

There is a spray that you can apply later on. So when you wash the car the next time. Dry off the car, the apply the spray. Which is even easier to you than the wax.

You can go nuts a by the whole NXT line...
I have the tech-wax and spray and can attest that they work. Very well... and no I don't work for them or anything related to car products.
