riskus,
Congrats on your purchase, VW is making some really sweet cars these days. I love the new Passats, they are basically Audi's with the VW badge.
Anyway back on topic. Since you have a black car, you will soon find out that many many things will scratch it. Here are some quick tips to keep it looking good:
Use the 2 Bucket wash method to aviod swirls. This method has 2 buckets (duh

) one has your car wash shampoo and water, and the other bucket has clean water. Wash one panel of your car at a time, and then rinse your mitt out in the clean water bucket. Do this after every panel, you will be amazed at how much dirt gets on your car.
Don't use cheap towels on a black car. Invest in some quailty towels. Microfiber and cotton are best. Magic/Miracle towels are awsome for paint. You can get them here
www.properautocare.com or
www.tacscar.com . Cotton towels are also great for helping to dry the car, and for other various uses. Get good ones, I personally use Fieldcrest Charisma towels. These towels are very pricey in department stores, around $19.99-$24.99 per bath towel. But, you can get them from the Fieldcrest outlet for much cheaper.

You don't need to be nervous about using Klasse. Once you get the hang of it, you will love it. Sometimes I can't help myself and feel the need to apply more layers of Sealant Glaze, I think I am addicted

I suggest you use the Search feature, there are tons of threads about a wide range of topics and products. They range from just the basics to advanced applications of different products.
