How do we remove the exterior chrome chrome trims? The one on the bonnet, on the doors (right below the windows)

Do I just pull it directly up? or do I need to unscrew anything? Thanks!

 

you don't remove it, you cover it.
there's vinyl tape available to do the belt line, most people use plastidip for the badges and emblems, the light rings can either be wrapped, plastidipped or painted. the door handles are a little tough.. vinyl doesn't contour right to them, plastidip gets scratched off and they're expensive to paint. you can get a set of blackjack covers and paint them and that would probably be the simplest solution.

dig around there's quite a few plastidip threads.

 

Depending on the look you are going for, plasti dip is matte black, vinyl & paint can be either glossy or matte. Plasti dip & vinyl is non-permanent & paint is permanent. There are instructions on how to remove the pieces all over forums, just do a little searching.
