I would say that unless the worn off finish is causing problems like the lure taking on water to leave them alone. Yes those nice new custom finishes look good but like Raul was saying my best baits are trashed. Without telling me I can look into any tacklebox and tell what you best baits are? They are going to be the ones missing eyes, paint, faded but have new hooks. I have 2 plastics baits that for some reason out perform identical baits? One is a Mann's baby 1- and the other is a RC 1.5 that I would not sell for $100 each. The Mann's bait hunts and will outfish the other 12 I carry combined. The RC I have no idea why it works better all I know is that it does?
