Older Honda with Sunspots
 

My 2005 Honda Accord has been parked outside most of it's life. About 5 years ago, what I think are sunspots started appearing on the paint. They are quite large. I wonder if this is related to the special coating treatment I bought when I first purchased this car. Has it reacted to the outdoor conditions? The car has 90,000 miles on it and runs very well, but it looks terrible. I imagine what is needed is a new paint job. Has anyone else experienced this?

You'll have spots when on your last leg.
