Thanks for the advice guys, think I will go for a combination of 2 part filler in the small cracks and some fix-all in the bigger ones.

Unfortunately I can't just replace the pieces as it's all the bottom and mid rails on my drive gates, this photo might make it a bit clearer when you can see the hinge.

The gates have never had much attention as they were only meant to be temporary till I made the proper ones, 6 years on they are still temporary :|

But they're high modulous (ie relatively inflexible).


But CT1 is flexible? Or am I getting the wrong end of the stick?
This is from the CT1 website..

Are there? I didn't know there were low modulus silicon sealants which could be painted. Obviously that would demand a highly flexible paint, at least as flexible as the sealant.


Well quite - and there's the rub, I think if those gaps were filled with something flexible, the filler won't be the next issue to deal with.

Phil - on the few occasions I've had to do a deep patch / fill with 2part in wood I've also really soaked the soft wood with hardener, drilled out some holes and soaked those as well with a syringe for deep penetration, then plugged those holes with hardwood then soaked again and put screws with washers there to act as ties, then filled it all. I've done it 5 times - 3 for a "get us through the next 2 years before we replace the whole lot with UPVc" and 2 times at my parents house a couple of years back, and so far at least those 2 seem fine.
