how do I get a 'Dynamic shine'?

Ok, I know how to make reflect maps, but I have noticed that on the stock FS2002 airliners, there is a different type of reflection map on it.
for example, if you look at the reflections on the Cessna 180, compared to the reflections on the Boeing 777. the reflect maps on the Cessna are like a glossy, and reflective, type of map, but the ones on the 777 instead of reflecting, just show up like a highlight, or a 'shine'.
i use g-max, in order to get that look do I need to make a different type of material?
I hope I make since, and thanks for any help
