Hi @camprojects,
Thank you for your question and welcome to the Bunnings Workshop community, it is fantastic to have you with us.
As the Marquee Cape Cod Timber Chairs come painted, the paint acts as a protective sealant so there is no need for any additional coatings.
To keep them looking good, you can use 30 Seconds 1L Outdoor Cleaner Spray every month or so to give them a good clean.
If down the line you want to touch up the paint, you can apply a fresh coat of Dulux Weathershield Vivid White Exterior Paint.
Let me know if you have any further questions.
Jacob
