I posted this in the "Yellow Filled Roll Stamps" thread on December, 30. This question seems to come up about once a week if you pay attention!:
"If the lettering fill is gold colored it is probably "Bonanza Gold", still sold by Forster, the reloading manufacturer. There is also "Bonanza Silver" from the same source. They consist of a clear lacquer with either silver of gold colored "Bronzing Powder. They are easy to apply or to remove and do no harm to the gun. These products have been available since at least the 1950s, and at one time were quite popular. To call filling of the roll-marks "vandalism" is, at best, silly! People fill the lettering on their guns for any of several reasons, all legitimate!
In addition to these two products There are also paint sticks available in many colors. The most frequently seen are white and red, although yellow, orange and other colors are available.
Besides filling the lettering "Bonanza Gold" can be used to fill the top half of the serrations of the Baughman type front sights. This creates an effect similar to having a square gold bead installed in the sight. This is quite durable and easily renewed if it wears off."
