Apologies if this is one of those regular questions (I did try the 'search' first..)

I'm getting my thoughts organised for building my first strip kayak. Due to the cost, and obscurity of supply of bead and cove router bits here(New Zealand), I'm planning to bevel the strips. Yes, I've seen the conventional wisdom that suggests using B&C on the first boat, but I'm up for the challenge..(I think..) I'm also keen to go the stapleless route, and maybe try out the fishing line technique - and failing that, maybe some hot-glue.

From what I've read on this forum already, it seems that getting bevels right is an aquired art, and an apprentice like me will probably end up with some unsightly gluelines once all is faired.

So, I have a couple of questions for the resident experts:
1: What glue to use between the strips - given that all will be sealed and watertight under the epoxy, is something like a waterbased aliphatic PVA suitable for the job, or is there something better that I should look at?

2: Given that my first boat-load of bevels are likely to be of less than perfect precision, would mixing some wood flour into the glue at the start be a viable option to disguise the gluelines? Or would that weaken the join too much?
