Just a FYI for everyone.
To cover trades use black putty like Uncompany.com does. Then simply take it off when needed. The constituency of it is like that stuff you use to isolate windows, except when you take it off, it simply comes off as a 'strip'. You can buy that stuff at modeling/art stores in a couple different colors (if you gun is black, you will need the black kind).
