I tried masking the tach needle first in the pic above and you can see one step of it in one of the below pics, but had to come back and redo it.. There's no masking stuff that small and getting the result I wanted.
I just sprayed over the metal with matte clear to keep with the original look, I was tempted to spray it aluminum though. New circuit installed here.
Changed out my hi-beam indicator to green to match the needles and other green accents I've done.
tach needle came out nice since I took it part.. was a little rivet holding the 2 pieces together. I put it back together with hot glue. That's a piece of white lint back there oops.
All done. New glass, faceplate and circuit... I tried to polish my old glass but it was too far gar. I'm going to order some green 168 bulbs to out in here too.
