Instrument Panel problems of the 1997 Chevrolet C3500

Issue number 1: the paint on my 1997 k3500 dually has been peeling away consistently for the past couple of years. I have had areas repaired before, however, the areas not repaired are peeling as well, as though the primer coat is defective. Issue number 2: it has come to my attention that the speedometer/odometer is 10 miles an hour faster than it should be at 60 mph, which has racked up numerous miles on my vehicle unnecessarily, and putting me out of reach of the extended warranty back in February 2005 when my transmission needed replaced. I have always been a Chevrolet man, but I am re-thinking this logic at the present time.
