Need help with a/c metal surface highlighs/effects please

[Mangas]

Hello to all.I'm making a color profile of the IJN Aichi D3A2 "Val" dive bomber.The main details are done, but I really stuck with making the proper look for the metal bumps effects and the panel lines highlights...http://imageshack.us/photo/my-images/526/d3a2wip2.jpg/Here's the example photo of the IJN A6M "Zero" that has the effects I try to make. Besides highlights, any suggestion how to make those "uneven" dots effects near the rivets lines?Any ideas how to make these in PS?http://www.j-aircraft.com/walk/rod_larson/Zero-Ground-8.jpg Thanks in advance. Sincere regards, Mangas.
