Have seen some lovely patio furniture which is wood but painted with white polyurethane paint. Firstly, do you think this would be maintenance-free - you wouldn't have to oil it like you do with unpainted wood, would you?
And secondly, do you think it would go all yucky and dirty over the course of the year (it would be left outside, though could be covered in winter). It looks lovely now but I can imagine it being grey and paint cracked come next spring...
