Web like spots on RV skin

Does anyone know what this is (picture attachments)?...It has started to appear in several places on the skin of my 2009 International...How does it start? Is there a remedy to stop, or treat it?

Thanks in Advance....

It starts here: Corrosion problems with new Airstreams

You've got it pretty bad. Read the Corrosion thread listed by Silver Gate above. You can stop it. Repair is difficult, but possible with results that are not to bad. A good bit of work though. I've repaired several places on my 2012. Details posted in Corrosion thread.
