Those logos can look good. Most are worn out chrome and all. Here is what I
did. First, they are  easily removed by gently prying them out with a puddy
knive covered with a rag.Clean em good. Spray with a satin black spray can
from advance auto or other flaps. Then go to a auto body supply house and
get a  spray can of wheel silver paint.The stuff at advance is not the
right color. Next , get a paint roller from Home Depot. A small one about 3
inches is width. Spray your roller with the silver paint to load it up.
Only takes a small amount.Next, carefully and softly roll the logo with
this. The raised vanagon , and volkswagon  letters will get the paint,and
the lower areas will stay stay satin black. you can screw up a few times an
repaint the black areas. Then try a rerolling again. I did it second time
just right. I got a wood bock of 2X4 and drilled 2 holes in it for the
prongs on the rear of the logo to stick into.This made the log lay flat and
even.The results are very nice,and cheap.
