I have a customer looking to have their store information put on their window placed on the inside of the glass with gold metallic vinyl. I am looking to get recommendations on the brand of vinyl to use for this as I am looking to have the gold on the adhesive side for it to show through the glass (to the outside of the store). There will be a black drop shadow outlining the lettering so the gold will not be showing on the inside of the store. Thank you for your input.
