I spoke w Porsche Canada and they told me spraying my Cayenne w/ KROWN will not void the warranty HOWEVER IF it is found that the KROWN caused the problem than it will not be covered. Fair enough.

If anyone has been told different please explain

Anyways, I have sprayed w KROWN many heavy duty pickups, Freightliner Tractor Trailers, Escalades etc and NONE have ever suffered a rust spray related issue. I swear by annual rustproofing. All vehicles look mint brand new. Porsche tells me its not required. Whatever. Here in the 'Big Smoke' we get our fill of salt spray....this past winter every parking lot i saw was white, this new salt spray is filthy, its got to take its toll.

Ive read on some threads that Porsche uses a wax that may not react well with the spray. Anyone know anything further about this?

Has anyone sprayed there Cayenne with KROWN?

Thoughts?

Thanks in Advance
