Hi all.
I have 4" x 2" tanalith timbers I've used at the perimiter

much mating.
Glueing seems like not a good idea. *So can bog standard exterior
filler or
even car body filler be a better way of 'glueing' these joints?
Or something else?

Nether of those will add any strength to the joint (though "joint"
seems a bit of an overstatement:-) *If it's mechanically stable use
nails or screws. *If it isn't (though I can't see why it should want
to go anywhere unless you've REALLY botched the joint) I think you'll

If you want to make it look pretty with filler, that's up to you.

I intended to strengthen the joint with 3 or 4 screws as well as
'glueing'.
The filler option seems right in order to gap fill to prevent water
getting inside the joint to undermine it.
