Want to paint the car but don't know whether or not to take moldings off or mask them. The lower door moldings have to come off to fix the rust so Iknow I'll have to spring for some new clips there. Are they difficult to reattach? The roof rails? Do they just pop off similar type clips? and they appear to be made of metal and go down each side of the windshield. Should I leave them alone? I ordinarily like to remove as much trim as I can but I won't if it's too much trouble or expense. Any tips?
