I've got a nice blaster pistol I've put together but I'm just not happy with the silver in it. It's convincing enough for most people but I'd like something to make it shine a little more. I know R&B does wonders on armor but can it be applied to blasters also? Mine has a lot of hard to reach spots and crevices. I've heard R&B needs a good friction going that I'm afraid I won't be able to generate on parts of the blaster. Any suggestions? Should I sand the already smooth plastic before hand? Thanks for the help.
