What are you guys using to bring the silver back around the squares that house the gauges? I used to know this, used to do them, but it's been so long I can't remember! Some type of magic marker I think....
I use Molotov paint markers, from any hobby store or Hobby Lobby. Be careful....they take days to dry completely. Be sure to whipe it down with wax and grease remover first, and I also like to go over again with alcohol.
