Are you really going to repaint them 4 times?
IF so maybe experiment with water color for white so you could wash it off instead of repainting. You probably don’t need to paint it all white either, just the large flat areas to make it look like rushed paint job.
OR use white masking tape?????????????
If only these little tanks were remote controlled we wouldn’t have to base them. If they could also shoot little shells we wouldn’t need to roll dice.
Tired is enough.
I like tiny miniatures
