I'm looking for a hyper black silver look, is there a way to do this to the Nissan emblems that will last and look nice?

 

This is probably an idiotic suggestion, but maybe black permanent marker, wiped or applied thin? Sorry, I used to be an artist (many moons ago), and used to do that sort of thing on metal and I think it gave the look you're going for, but I will say I never did it on a car and I realize it might not be what you're looking for. You might try it on the back of the emblem to see if it works.

Sometimes silly, inexpensive things like that look good, heh.

When I still had emblems, I just had mine smoked at a body shop

 

tail/headlight tinting spray

or if you're going for the black chrome look, i believe duplicolor makes some interesting 'annodized' looking paints

 

just wanted to mention - i took the tinting spray approach on the emblems of my previous car... until i sold her (2 years worth of rain, snow and sun) it looked great. Even if it doesn't last, tinting sprays (i.e from foliatec) cost 8 bucks a can and it's easy to reapply.

makes dull aluminums look satin and chromes look hyperblack
