Myself not being a great model builder still notice that many times people forget to either drill out the exhaust or at least paint them black on the ends to improve the looks. Also the inside portion of scoops are not treated to a black inside. The body vents below the windshield can always look better with a wash of the detailer. Lastly, detailing wipers can make a big difference. I have forgotten these things more times then I care to mention.
