BlackAcc02D,
I'm both sorry and really surprised that you are getting the results that you say. I've never had anyone say that their car has started to oxidize. The effectiveness of 5 Star has nothing to do with the climate that you live in. The only reason that I can think that you have gotten such drastically different results than others is that something went wrong in the application process. We recommend that people who keep their cars outside begin the application process first by claying their vehicle to prep the surface. With any finish protection preparation is the key.
Maxboost is currently doing a review with pictures in which he prepped his car with clay before the process. I guess his finish was pretty dirty since he said that it took him quite a while to treat his car. He should be chiming in this week. He's had it on his car for a month and a half which is when you said your issues started.
