The only problem I have with getting blanks or custom painting stock baits is the temperamental weight of the bait when it comes to jerks. Paint/clearcoat can add a lot of weight to bait and when just fractions of ounces affect buoyancy it can cause a jerk bait to either sink like a rock or not suspend exactly how you want it. You can add suspend strips/dots of course or add weight somehow to get it to slightly sink or remain suspended but if a bait is too heavy you can't really make it float (other than using lighter components, thinner wire hooks, split rings, etc). I bought some knock off Lucky Craft Pointer 100 SP blanks from Predator Bass Baits years back and had them custom painted and they sunk a rapid pace (think Rapala countdown). Were more hassle than they were worth.
