I have an Ultra Low Mile GN with under 2,500 miles and the original fillers look like crap. They are not cracked but they lost the luster and turned a gray/dull color. I know it is original and 100% normal for this to happen but I ordered the newely made fronts from NOS4GN.com (from the original mold with the original material) and the G-BODY rears that are a near perfect match to the originals in both fit and material. The question is should I take off the originals and put on the aftermarkets?
