I have 2021 Denali 1500 7 month old. I noticed where the clear protective coating on the panel right in front of the rear tires, was full if chips, through the coating and the paint. I thought this coating was hear to protect the paint. I have not driven on gravel roads more than a couple times. Ther are no chips out side of the protective coating, pretty much start where the coating is applied . I showed the local GMC dealer body shop , and his response was " what do you want ne to do about it" He was a real dick . Just wondering if others have had an issue, or is this just normal wear and tear as the dealer seems to think. Seems this shouldn't happen in 7 month in normal driving conditions
