yes there is its called clearcoat you can get it in a spraycan at your local hardware store use light coats to gain sheen rather than heavy coats or you may end up with runs in your finish

Ok so most of you probably won't know of this, but i have these Gold Keys that I bought online. They are based of an Anime called Fairy Tail. When i first got them they were nice and shiny, but after a while of wearing them the gold is beginning to fade into silver. The material is a very high quality alloy that would give you a concussion if you got hit in the head with them lol

I'm wondering if there are any type of sealers that i can put on them that won't alter their appearance. If you know of anything i would really appreciate a response.

Thanks :)

Sorry if this is the wrong section.
