as far as metal showing on the lasers, it's possible that there was no metgal to shine through. The weapons could be a carbon fiber or polymer construction.

I know we all want to ignore Galactica 1980, but when Troy and Dillon were boarding that airplane to go to NYC, they talked about going through a metal detector with their (small) laser pistols. It was mentioned that they weren't metal but plastic.

you won't get the same worn look like you do on Star Wars blasters, but you can still dull them up.

But Very nicve looking laser my friend.
