I need to know if there is a deck sealer that I can buy that will look like deck is polished.?

I have a large wooden deck built onto the back of my house. It is made with treated wood about ten years old now.

I need to put some water sealer on it but want one that will make the wood look like it is varnished maybe with a little stain added to it.

I tryed small section with sealer and it just looks like i put maybe linseed oil on it. I do not want this.

Tell me is there a sealer that will make it shine???
