Garden fence and shed paint / treatment recommendations

sec79

Hi, Looking for recommendations for the best type of paint to use on a fence and shed which will protect it from the elements and ideally waterproof. Is it worth paying extra for Cuprinol Ducksback or Ronseal Fence Lifeplus? I don't mind paying extra if it will last for the full 5 years, but if the fence and shed will need repainting after 2 years wondered if I should just purchase the standard Cuprinol or Ronseal. 
The fence was installed 5 years ago and I figured it needed painting to protect it and so it last longer. The reviews I have read are mixed so it is difficult to gauge if the product is any good or not.
Thanks in advance

I've used all sorts on my shed over the years which only lasted a year or so but I used Ducksback about 3 years ago and it shows no sign of deteriorating.

I guess whether it's worth doing all the fencing as well depends on the price difference and length of fencing.

I've found Ducksback works well and it is the more environmentally friendly option, but you need to pay attention to the preparation to remove algae and loose paint to ensure it lasts. It goes on like brown emulsion, a paint coating on the surface.

The oil based treatments like the creosote substitutes have the advantage that because they soak into the wood rather than coat it, they need less preparation, just a good brush down which makes it easier to recoat them. They do smell though, and often for quite a long time afterwards, well based on the creosote substitute product I used.

If you go the 'creosote' route, be aware that most products are not true creosote because the EU restricted it so it's only available to trades people and farmers, most of the products in the DIY chains and outlets are creosote substitutes using inventive naming.
