Something else to try would be to lay out the paint in a pattern on a board and then role the lure on the paint. I honestly don't know how well this will work but it may be just the trick. Just make sure to lay a thin layer of powder down. Maybe try it on a sponge with a light weight cardboard so it will bend and mold to the shape of the lure for complete coverage. Maybe aluminum foil on a sponge will work better.
I need to try some of these ideas for myself. I am just better at the thought process than doing it while I have the paint out. Good thing I write about my ideas here or I would forget them all.
I love taking my kids fishing, now if I could just manage to fish at the same time.
