The main aim when developing our bait sprays was to make them complement and match the range of hook baits that they are dedicated too. Using the matching flavour palatants accompanied by natural attractants, I believe they are best suited in making your chosen hook baits even more potent and attractive to the fish. The way we would recommend using them is by spraying three or four times directly into the tub that houses your hook baits and giving them a good shake in order to give a nice even glaze over each bait. Over the next couple of days keep shaking the tub every few hours and allow the hook baits to totally dry out. Once fully dried, repeat the process again. I would do this process no more than three times as anymore will reduce buoyancy if enhancing a popup or wafter.
There are alternative ways to use the spray, they work extremely well leaving your zig foam or plastic hook baits soaking in the liquids.
