lol...
think should be something like this, taken super long ago... the only 1 online now...
idea is simple... if its reflective like a mirror, then u user reflector... no matter how reflective a cylinder is, there is always a blind spot. if u shoot long enuff, u can find that spot. Unless your customer specifically want to shoot at that angle. then u suay... then you have to use 1 big piece of cloth or plastic sheet as reflector, smooth straight and continuous. then for the black part, use gaffer tape or black tape and tape over the reflector.
