Heed this sage advice that others have stated and you'll be fine.
An easier to find alternative to Novus is Plastix by Meguiar's. Available at any auto parts store. Same thing as Novus 2 really, except it's light blue instead of light brown. I've used both and I'm just as happy with Plastix as I am with Novus. I tend to use Plastix more often, just because Novus can be tricky to find locally.
Novus #1 really helps bring out the luster and depth of wraps. It's basically Windex specially made for plastic products, but it repels dust and fingerprints too.
Another item you might try is 3M Medium Duty Headlight Restorer. I've used this and it makes the wrap very smooth and feel like brand new, and also adds more depth to the wrap as well.
