Was wondering how long the paint or corrosion warranty was on a 98 SLK. Never seen this before, the paint on the rocker/cam cover is bubbling and is cracked and pealing in one place. A minor thing I know but it's bugging me. The car has 44000 miles with Full Mercedes Service History. I read somewhere that Mercedes have a 30 year corrosion warranty so would this apply here or was the warranty given with later cars? Thanks in advance.
