Welcome to the Bunnings Workshop community. It's superb to have you join us, and thanks for sharing your question about your deck.
It sounds like a very interesting product, unfortunately, I believe it is only available overseas. At the moment I'm currently not aware of a product that does exactly what you describe. However, for long-term repairs and upkeep, I still recommend sanding the surface of your deck and using exterior-rated filler to cover any damage to the surface of your deck.
