I just bought a 2002 Silver Xterra SE/SC and the paint seems to be in great condition, but since I am new to detailing, I want to start things right.

My question is, since I have been looking at all the posts about different waxes, clay barring, etc, I really dont' know where to begin. I really dont' feel any rough spots or bumps that would indicate needing to clay first, but I can also tell that the finish has not been waxed in a while either.

Do I start with using the Cleaner/Wax first & then NXT or can I go straight to using NXT since I believe the paint to be in good shape?

Thanks for the help?

P.S. How does NXT Trim Spray work on the exterior trim (gray color on the Xterra)?

You can get a lot of opinions on the web. But I think your best bet would be to contact the manufacturer directly:

In addition to the wax, get the right 'tools' to work with. For example, a towel with synthetic fibers can scratch the paint. Get 100% cotton.

dave and xtoy - don't do more harm then good

What I've learned is start out with the mildest chemicals (wax/polish) for the result you want to achieve. This may take a couple of applications from mild to harse but better to go over it a couple of times than burn through the paint the first time.

Thanks for the advice, I did a post on the Meguiar's forum and was told that I should either use the Cleaner/Wax followed by NXT or clay followed by Cleaner/Wax then NXT... either way, I need to do the Cleaner Wax first so that will be my first project!
