Noticed the other day that the bezels on my 67 were discolored. I almost felt ashamed as I drove home that I may have been disrespecting the Nova for an undetermined amount of time! Tried simple green, rubbing compound, and NeverDull so far - wont budge! Anyone seen this before? other products to try? Just trying to avoid spending $200 on two new assemblies... but I absolutely will in the next few days if I cant resolve this!
