Paint Discoloration

[Grandpoobahh]

Has anyone had problems with their paint yellowing? I have a White 2005 LR3. After a weeklong trip down to baja, I spent an hour and a half washing her when I got home. There are now about a half dozen light yellowing spots on the paint that seem to be under the surface and won't wash off. They are about the size of my palm, irregularly shaped and at random spots around the vehicle. I haven't taken it to a detailer or the dealer yet to ask, but this seems pretty strange.
It has 7,000 miles on it and I've had it since March 2005.

Try a clay bar kit like this one http://www.meguiars.com/?auto-detailing-clay/Quik-Clay-Detailing-System works wonders
