Painting some imperials

I’m trying to paint a pair of imperials using oil-based paint, the kind used for arts and crafts. The paint takes days to dry. I’m not very knowledgeable when it comes to paint, so if there’s any better alternative paint/method please share.

Someone with more experience might correct me, but I’m planning on using paint for plastic model kits to experiment on some old Mosquitos I have lying around. (By hand, not airbrush). That dries fairly fast.
