This question on warranty and rust proofing has come up several time on several different threads. If someone will definitively provide us with substantiated information such as a dealer letter etc. we can put this to rest.

As a side note here, when I purchased my S4 I asked the dealer about rust proofing and the sales guy did say it would void warranty. This however is the word of a sales person.

Thanks
