I read on here a while back recommendations for an oil based paint for outdoor wooden windows. I couldn't find the post but thought it mentioned Dulux Weathershield. I looked for this but it seems to be for walls not wood. Could anyone point me in the right direction for a top quality paint for this job. Thanks.

You can't go wrong with just about any premium brand. With wood, you will need to prep with a good sanding and sealer, with light sanding between coats for the best finish.

until we changed 99% of all our wood windows and doors[40 in total] I used toa supershield gloss enamel it was ok.but you still had to use elbow grease every so often to clean them.now I have only the front poach double doors and some facia's to paint,done them a month ago and they look very clean and glossy,i used captain enamel gloss from home pro,went on very easy.
