Hi all.
I have 4" x 2" tanalith timbers I've used at the perimiter
(lying flat) of my shed base and they are connected at the corrners
with
lap joints. I had to break apart 2 of the joints to resize the base
and now have to fix them together again. And as it happens I used a
hack and f*ck
it method of carpentary so the mating faces of the joints don't do
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?

Thanks.

Arthur
