ive got a great idea for this , you can get this stuff called embossing powder and an ink pad that comes with , its normally use for craft like card making ect but works on plastic glass wood ect you normally put the stamp into the ink pad thing then put some gold embossing powder on it , it sticks to the ink stuff then you get a heat gun and heat it and it turns into gold hard stuff so i reckon if you get a stencil if the lettering and a stippling brush and stipple the ink throught the stencil, then pour the powder on use the heat gun your in business gonna give it a go myself when i can work out how to make a stencil
