"MACTRAXX"
To me a "wrap" is something meant to be temporary - a clear coat to protect the aluminum body
makes good sense and would further protect the car from deterioration or vandalism (graffiti for
one) and perhaps extend a car's life span.


Aluminum needs no coating to protect it from deterioration, It naturally forms an oxide coating to protect itself in much the same way red metals do.

The wraps are a low cost method that eliminates the use of environmentally unfriendly detergents and solvents to keep the exterior of the aluminum car bodies brightly clean. Those detergents and solvents removed the dirt and grime not the naturally formed oxide coating.

From what I remember, Metro would have had to treat the dirty water if they wanted to use detergents to wash the railcars. That means a treatment plant at each wash location that would have to comply with the local jurisdiction's environmental effluent codes. That becomes expensive and cumbersome to manage.

The wraps are only for the sides of the cars; the ends and roofs are not covered. I remember reading a while back in one of Metro's long term plans to change the livery of the legacy fleet to reflect that of the 7000 series cars.

I remember some people giving the wraps a lifetime of few months, max. We're still in that window, but the wraps appear to be holding up well.

There are wraps and then there are wraps. The new look vinyl wraps on the rail cars is basically the same as the livery on the Metrobus fleet that also is done using vinyl. Advertising wraps typically include inkjet printed artwork that will degrade when exposed to weather and sunlight.

Caught wrapped pair 3070-71 today at WFC Junction, and I think I’m getting used to all-silver liveries. (Much more so than the multicolored door advertisements.)

On my last trip to DC in April, I haven't seen any new repaited (wrapped) units but when I go there during this summer I hope to catch some new repainted cars

I still don't see these wrapped cars very often. Saw two last week at Stadium-Armory.

When they are expected to complete wrapping all the cars?
