Toyota Camry 2005: Cloudy paint on rear spoiler

As a regular reader of the Carsguide, I have noticed quite a number of complaints from owners in relation to paint defects. My black 2005 Toyota Camry Sportivo is developing a clouding effect on the top of the rear spoiler. The paint surface is not breaking down, nor is the clear coat cracking. It seems to remain on/under the paint surface. The car has always been garaged. My dealer has informed me that because it is out of warranty this problem cannot be addressed. I can clearly remember a reader having a paint issue with his Renault whereby Renault Australia offered to cover half the cost of repainting his car, yet Toyota won't even look at my car. What do you think?
