If you don't want to do wholesale paint jobs, you can easily tweak/enhance existing lures and spoons with nail polish.
Lots of colors are available. Just paint with them, let dry COMPLETELY, then clear-coat them with any good gloss clear coat in a spray can.
3 thin coats of clear are way better than one or 2 heavy coats.
Don't breathe that stuff---hang the lures to dry in a well-ventilated area or on a string--like a clothesline in your garage.
