Don't bother with it. We had it applied on our Corolla back in 1999 (it was cheaper to get one with it, don't ask). Other than making the paint slick for a few weeks, it was nothing special. To me, it's just a inexpensive sealant that is nothing but profit for the dealer. Additionally, the warranty is useless, there are many conditions that must be satisfied before you can make a claim. You also have to have a "supplement" applied every few months or yearly (I forgot the timeframe) for the warranty to be in effect.
Zaino, Klasse, UPP and EX-P are some good examples of commonly used sealants around here that yield excellent results.
