Decent paint/finish for external hardwood

[cyclonebri1]

Hi, my house is pretty much maintenance free regarding painting but I do have 2 very large 5bay bay widows to the front. They face SE and are protected somewhat by the overhanging veranda roof.
Now these were in 15 years ago when I bought the property, they were joiner made in some form of Mahogany by a well respected local outfit. They are quality and still as good as new.
Ok, I need a recommendation for a paint for them, previously I have used such as Wickes Micro porous mahogany finish and several others. Now my regime is to repaint every 2 years to keep these in good nick, I don't mind that it's not a big job and is the only external paint I have to do.
But what I do expect is for the finish to be perfect fror those 2 years and not absolutely matt and peeling.
Any suggestions before I search the likes of Sadolin etc?

Cheers,

Sikkens filter 7 is what I would recommend, thereafter a maintenance coat every 2 years would be fine but DO NOT sand down the filter 7 just wipe it down with a cloth and some white spirit.

Great, have heard of Sikkens, will find a supplier.

If you dont use the Filter 7, use the Sikkens THB in your chosen colour. Will not flake or come off, Very light abrading and coat up every 2 years. Will last for years.
