Removing old paints?

I have some old lures which their painting have came off after several trips (mostly hitting the structures than being bitten by fishes [:D]). I’m thinking of giving them new clothings, but don’t know how to remove the original paint.

Thought of using sand papers but afraid might damage the tiny details, and some paints were like “plated” on to the lures.

Is there any proper way to remove the old paint?

I come, I see, I fish!
