If you’ve ever wondered about the process for painting a shoretrooper helmet kit, this is the post you’ve been looking for. Paul has been working on a complete set of armor inspired by the troopers in Rogue One. For the helmet, he bought an existing base from Back Stage Props and only did a little clean up and finishing before he painted it. Though his tutorial is specific to the helmet, it of course has techniques and information that can be applied to other projects.
He started with filler primer:
Shake the can well and apply in light even coats. Take your time and do not rush it. Leave 25 minutes between each coat until completely covered. Do the same with the forehead piece. Do not paint the cheek greeblies or snout. Put them to one side until later.
Give it a 2 hours to dry properly. The filler primer will fill any minor imperfections and at the same time highlight any raised areas that may need further sanding. I used a fine grit sandpaper to rub down the filler primer all over every surface until I was satisfied with how it all looked.
You can see what the helmet looked like before painting below.
