I am working on my first build - Drakkar by Amati. Part of the build involves painting 24 viking shields. Shields are round but not smooth (I've attached a picture), so even tape might not help much. The center and outer ridges are raised. Ideally, I would like to make center and ridges bronze/silver/black (whatever is easier due to paint application order) and the main body broken into halves or quarters with different colors. I was wondering if anyone can suggest a method or approach to avoid doing all of it by hand (what I mean is I would like to have straight color borders with no smudges, don't care if it is by hand or an airbrush). I found several logs on MSW with shields executed perfectly, but no method of painting was discussed. Keith (Amfibius) mentioned that he had to do it by hand, but I am afraid my hands are not as steady as his. Is there any way to create some kind of template? I was thinking of simply creating a round paper template with the hole in the center to airbrush center and ridges, but it is still leaves a problem of separating colors on the main part plus paint leaking under the paper. Any advice would be appreciated.
