Hi @isaac95,
A warm welcome to the Bunnings Workshop community, it is fantastic to have you with us.
There are food-safe clear sealer products such as this Clear Gloss Benchtop Timber Finish or oils such as Gilly's Chopping Board Oil but unfortunately, I am not aware of any food-safe spray paints.
If you can provide some details of what you are trying to achieve, I can potentially find an alternative solution.
Let me know what you think.
Jacob
