While this could be considered tangentially related to threads in the Showing Off forum, I thought it fit better here. (I could be wrong)
In the past I've bemoaned the painting that's been done on some of the figures we've gotten for the minion (many of them not having any at all on the backs, so Cap's back is solid blue), and have thought about fixing it, but have had some procedural hesitations. Now that we've found an Imaginext playset at Goodwill (can't beat the price) that has lots of detail all in the basic plastic color, my desire has been re-awakened (and tentatively okay-ed by Mrs. Gunn). My two main concerns are:
1: What type of paint to use. While I find the water-based paints typically used for minis to be easier to work with and generally non-toxic, it does have issues with durability and coverage (painting anything that hasn't been primed either white or yellow is always fun, sometimes even if it's been primed). The minion is still pretty hard on his playthings, so I don't want it all wearing off too quickly. Oil-based model paint will conceal more, and should be more durable, but I feel I have less control with it, and it's a little more of a production to use.
2: Masking. Way back in the day when I was painting models (mostly cars) I would use tape to cover areas that I wanted to not paint (either already painted or I wanted to keep the plastic color), but I would routinely have issues with bleeding under the edges, and it's not much fun for anything that's not a straight line. My brush skills aren't the best, and when I paint minis I tend to go with the "overlap & touch-up" method, since the whole thing was getting painted. I don't have an airbrush, and am likely to never make that move. I don't feel like painting the entire surface of these relatively large items.
For those that re-paint figures, I would love some input and suggestions, especially, since this relates almost directly. If I ever get around to actually doing the project, I'll post before & after pics ......... unless the after turns out to be completely horrible, in which case you'll never hear about it again.
