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.
