Recommended Exterior Filler for Wooden Guttering

[Antony2008]

Last year I repaired a sizeable hole plus other minor repairs on my original wooden guttering using Wickes products - Wet Rot Wood Hardener & Exterior (super tough) Wood Filler, following the instructions implicitly - removing all rotten wood back to a solid base, treating with the hardener & leaving overnight, followed by applying the two-part filler, after which two coats of Dulux Trade exterior undercoat then top coat were applied after sanding smooth. Unfortunately one year on, the sizeable hole is now dripping and the minor repairs haven't lasted the test of time either. Subsequently, I'd appreciate if someone could recommend a suitable filler that will do what is says on the tin...!
Many thanks in advance.

I would not attempt a repair on wooden guttering once it's got to that state, simply replace.

its because you are trying to kill wet rot fungus with two pack in a damp environment, no contest

Many of the wooden gutters up this way originally had a lead lining, I think this is the case in most areas too. These have mysteriously vanished over the years and now most gutters round here are extruded seamless with a profile that is similar to the original.

+1 for replacing as soon as possible.

This could be the last post on wooden gutters

Use GRP with matting. Last for decades.

Many thanks for the replies to date.
Have to say it would be a shame to replace the whole lot due to a relatively small dodgy section. Replacing it wouldn't be a problem if I wasn't in the middle of physio for 'bulging tissue' in one of my discs, hence the need for a speedy straight-forward repair. Subsequently, given the sun's out today I'll zap the offending areas with a propriety ('tho I'd assumed the hardner would have treated both kinds of rot) wet & dry rot killer - see reply from Harbourwoodwork - then have a look for a suitable exterior, flexible filler (I'll include GRP products (joe-90) in the search) and see how it goes.
So, this could be the penultimate post on wooden gutters.... - fingers crossed, if only for me not to fall off the bloomin' ladder!
