Thanks AirMech74!
Here' s most of the main body after weathering all the edges. Honestly, we could leave it at this level and it would look pretty OK. It's not far off from how the blaster looks a lot of the time (though it's even more scuffed in some episodes).
But let's take it up a notch or two.
After this stage, I scuffed up the surface with some fine steel wool, using straight movements with a very light touch. I also made sure that the scuffing was not uniform, leaving some patches more shiny and others taking off the blue topcoat, going down to the black underneath. Like so:
Next, the parts were covered in a rubbing of graphite powder, using a cotton swab, then the parts were washed in water and diluted (hand) dishwashing liquid. The graphite particles embed themselves into the paint, so they don't all wash off easily. (Sorry, no photo of this stage.) Inpsecting the blaster, I wasn't happy with the overall look- it was too "gunmetal" and uniform, so I decided to add more blue, and also some brown.
Going over all the parts carefully, I sprayed clear blue and clear orange over them, typing to keep a consistent method. This will help represent, in very subtle tones, the "oil slick" shifting you see in old blued weapons.
This is what that stage looks like:
Time for some more scuffing with steel wool and a little 1000 grit wetsanding paper, again with a
very light hand! This builds up a feeling of "wear over time" instead of it just looking like you took a scrubbing to it. And after that, another rub-down with graphite, followed by a thorough washing wish dish soap again. (This time I used kitchen towel paper, the non-lint kind like they use at gas stations or workshops, because it's ever-so-slightly abrasive.)
That leaves us here. Not too far from what I was aiming for, but still a little too much "gunmetal".
Here's a real vintage blued S&W revolver piece to compare:
At the time of writing, I'm not 100% decided yet on what I'll do next. One option is to do a weathering rub using black oil paint, which will tone down the shine and darken it a little, but most likely I'll do another spray coating, with Tamiya clear "smoke" with a drop or two of black added, to darken the overall look.
Note: Those of you doing a simpler rattle-can-only variant of all this can just ignore all thes extra stages... it's overkill, but fun to experiment with.
The rattle-can blueing method would simply be:
- black base
- dry-brush silver OR use a Molotow pen on edges
- spray clear blue
- scuff so that the black undercoat shines through in some spots
- coat with graphite
- wash parts with water+dish soap
More soon.
