No problem. Just make sure to set aside 6-8 hours for the complete kit.

 

Now you park it in the garage and stare at it and dont drive it for about a week.

After that first week go's by you'll be all ancy to drive your nice and clean Z, it'll be priceless when your at there attacking the curves

 

I'm not a big fan of zaino, I prefer meguiars or usually p21s. I bought my 03 used and the paint was so oxidized and dirty I've been claybaring, polishing, and waxing for awhile now. It's in the garage so I can take my time.
