Car Window question??

Hi.

I was "commisioned" by my Wife to build a "Love Wagon"(Toyota Hiace Wagon).
Now I seldom stray into the area of 4-wheeled civilian vehicles and was wondering what is the best method to do the black trim on the window panes.

Any good techniques, tips would be appreciated. The thing has PLENTY of Windows 3 in the roof alone.

Last Hiace I build was a custom van with most of the windows sealed up.

Any help/input appreciated.
