The front license bracket is normally attached with steel pop rivets, I wanted something that could be removed if needed but is still firmly attached. My local Chevy dealer was happy to supply 4 push pins that work like a pop rivet, but can be removed by pulling the expansion pin out.
The rear license frame had the Chevy bow-tie, but also the selling dealer's name and phone number. So I used my grinder to erase the letters and numbers, used a fine toothed file to smooth out the grind marks, and finished with some red rubbing compound and elbow grease. Call me frugal, but I am happy with the result and it only took 5 minutes. No, that's not my real license number.
My all weather floor and cargo mats have a nice Volt logo on them, so I decided to make them match my white console and steering wheel trim. I used PlastiDip's liquid Create Your Own Color ordered via Ace Hdwr and applied several coats using a mini, low nap paint roller (cut in half) from Home Depot. I don't know how long the white lettering will last, but then again I have 90% of the PlastiDip left. :-)
