Regular color or a metallic?

For mine I don't have enough room in my garage to do everything at once, so I'll be doing the door jams, engine bay and trunk seperately, then taping them off and doing the outside of the car. If I tape it off at the places where the body panels meet, ie where the fenders meet the inner fenders, where the rear 1/4 panels wrap around and meet the door jams, etc, I don't think the tape lines would even be visible.
