Hi Paul,
When fitting the battens, I first drilled the pilot holes, then screwed them in 'Dry' (no glue). Then when I was sure they were in the right place, I took them apart and squeezed a thin (4 mm) bead of PVA Woodglue down the center of the batten, and fastened them back in place with the screws. This squeezes out the excess glue and places them tightly in position, cutting out the clamping. Then, as Brian says, I removed the excess with a rag, sealing the gap.
Like walter, I had cause to remove a wrongly placed batten, and damaged the ply, so this is why I advise 'Dry' placement first, before commiting to glue!
Told you there are no 'Gormless' questions, just queeries!
Keep Busy,

Providing it is a 'Propriatary' brand, I don't think you should have any problems.
