December 6, 2013. I glued a casted face to the engine, like the ones on the tank. December 6, 2013. As planned, I put two casted faces on the tank to represent my Breaking bad theme. The placement of the faces protect the tank from the front axle when it is turned. The idea of the zip is to make the tank resemble the yellow jumpsuits worn by the characters in Breaking Bad. Etched Breaking Bad logo. December 6, 2013. The etched plates were glued to the engine and rear mudguard as shown. Brake pads on bike.
