>>59461991. Pry the visor out of the helmet using a small flathead screwdriver. Careful not to bend off its side which is thinner than the "body" of the visor which is a bit meaty. It's just weakish glue holding it in.
2. Sand it down smooth.
3. Apply an adhesive gold fingernail foil. I picked up a cheap pack on ebay.
4. Trim the edges of the foil off with scissors, clippers, hobby knife, kinda fold it onto the sides a bit too.
5. Glue visor back into the helmet.
