Rust Protection

[Joel Cohen <joelc@hookup.net>]

I got a call from my dealer today who informed me that I will be able to
pick up my Audi A4 Quattro in two weeks time <VBG>. That being said, I would
like to pose the following questions to those more knowledgeable than I:

1.  I know that my car comes with a 10 year no perforation warranty but
should I still have my car sprayed by Krown Rust Control Systems or similar
company to enhance the rust protection?

2.  If it is a good idea to have my car sprayed, who do you recoomend and why?

3.  Do such sprays pose any danger to the car's finish?

4.  Does anyone have any experiences they would like to share?

TIA,

Joel
