I think it depends on how you are approaching the bass. In instances where the fish can study a bait I think it may be helpful, but remember that bass can be terribly reactionary, have a super well-established lateral line and will hit simple movement even in dingy water seen or felt. I also think that a bass' eyes are more adaptive to dingy, dirty water so making something "brighter" might go the wrong way with bass. In clearer water the enhancement might help draw bass from further away by making the bait stand out a bit more.
Something to think about is the newness of this stuff and determining how much added is too much. Keep in mind that we cannot see the "real" effects of the enhancer, only the peripheral glow that is still in our visual capabilities, that bluish/purplish sheen similar to blue hi lite but without the pearling effect. It takes very little of the powdered Do-It plastic additive to achieve this glow, about a match-head sized ball in 4 ounces of plastic....and I am referring a book match, not the old kitchen match....in clear plastic and light colored transparent colors like chartreuse and hot pink, whites and pearls. On heavier, thicker, less transparent colors some playing is needed to determine what's enough and here everyone has their own threshold. The big problem most people will have is separating what they see from what the fish might be seeing - the fish do not register what they see like we do. What might seem "just enough" of this product to our vision may be overwhelming to some fish in some situations.
I'm convinced enough that this enhancer has a place here in the plastics world, but like everything else there is a learning curve. While the enhancers have been around as topical products for several years, putting it in paint and in plastics is relatively new technology. How much is too much is anyone's guess, but to err on the side of too little is maybe wise for now. The glow in color fad that came along in the last five years, especially in the ice fishing arena, brought along similar challenges. People got this paint and went nuts, coating jigs like no tomorrow. Then they said the stuff didn't work because the fish weren't hitting the glow baits. A camera or two down the ice holes told the story nicely: the fish would charge right up to the big balls of glowing pain and slam on the brakes to look at it, then turn and swim away. An identical bait with way less glow in the same color was put down the hole, baited identically, and the same fish was seen approaching that bait and hitting. I would guess that the same can happen with this enhancer.
I don't put eyes on baits other than those I am making new to me and those I plan to post pictures of. I do make a cover dip on at least 1/2 of the body with the enhancer added on my personal baits of that have solid bodies and on smaller baits I do the entire body avoiding the tail on all of them. This is the same dip I use on eyes and is how I deliver the enhancer without over-burdening it use internally on the less transparent colors. As mentioned, I add the enhancer to some transparent colors and the "whites" but the other colors I think do well with the enhance on the outside as a cover rather than in the plastic.
I haven't had a solid opportunity to use a lot of bass baits with the uv enhancer in practical settings yet, so much of my thought here is based observations from other fish in the "panfish" league. I have definitely seen a better bite using enhanced in several instances when crappies, walleye and sauger were being fished and I know as fact that the lake trout and salmon respond very favorably to the enhanced baits. I'm in the same league with Jerry on this idea that until we can create a dialog with the fish that's NOT human in interpretation, everything is based on speculation derived from observation. That said, I still feel the enhancer has a place and that bass probablt react to it too. It still remains to be seen how much of the stuff is enough and until a clearer picture gets painted, a little going a long way will probably get you more fish.
