If you have painted it already check to see if the paint is a decent
quality exterior paint. If not it almost certainly needs a coat of
something suitable to protect it from UV damage and weathering.

I used the Permaglaze MPV acrylic gloss paint, I've not idea whether it
his good quality or not (how does one tell?) but it does say it's
suitable for exterior use.
