After cleaning the board with lacquer thinner post etch, use a fine paste metal polish to shine it.
I use mothers mag wheel polish. It makes it very shiny. Then clean with dish detergent.
I sometimes may also hit the traces with silver solder to beef them up.
If you are making more than 5 boards the same, it may be worth it have them done in China. I have mine done there for about $100. (150 square inches total) delivered, takes about 2 weeks. That's for double sided with silk screen one side, same design. I won't give the name, or people will think I work for them. I don't, just happy with their work.
