How do i spary paint my plastic airsoft gun gold and keep it glossy? - airsoft gold dessert eagle

I think my paint gun G36 Spring Double Eagle gold. The spray paint is Krylon I Dorado. I do not know whether this type of chrome spray paint and glitter, but in gold. If the experience of someone with this color could tell me what is your painting is also welcome.
What I do is:
1.Clean weapons of dry dirt or dust with water and let dry.
2.Sand parties to spray the pads with scratches want.
3.Clean the weapon with alcohol on a cloth.
4.Spray gold with 2-3 or more layers of light to my meeting with the color. (With 30 minutes drying time between coats)
I ask myself is:
I need a coat of clear spray paint over the finished product to keep shiny and tarnish protection?
