I'm experimenting with vinyl wrap material with great results.
50 feet of 2" wide tape from Ebay $14
http://www.ebay.com/itm/370196741988?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649Clean up the emblem, apply the tape, and heat gently until the letters stand out.
I used a lighter, but scorched it a few times, next time is a heat gun or hair dryer.
Trimmed with X-acto knives, one pointed and one rounded scalpel. Don't saw at the material, it leaves a ragged edge.
Shown is the first attempt, the Vanagon badge. Not happy with a few of the letters, I'm redoing this one.
The VW badge is what I started with, typical grey & faded lettering.
The SYNCRO badge is the tape applied, and partially heat-shrunk (right side was heated)
Real chrome finish, easy to work with, and cheap. This stuff sticks like glue once you heat it a bit.
There's a huge array of colors and faux finishes available, carbon fiber, brushed metals, etc.
