Last weekend I finished off a print of the Ghoul’s pistol from the new Fallout TV show as part of a cosplay for the upcoming London MCM comic-con.
I printed everything using silver silk PLA. For the wooden sections I spray painted them brown, then mimicked a wood grain effect using a wide brush and a slightly darker shade applied lightly across it. And for the metal sections I experimented with a couple of different ways to make it look weathered. What ended up working was using some shoe polish applied lightly across the surface.
Then I used some of the gloss lacquer at the space to give everything a consistent finish.
If I had more time and money I think I could do better, and I think sanding and polishing the metal sections before applying the shoe polish would have been a little better, but I’m pretty happy with the results.
