If you have glued the wood together in it's 'raw' state, you may find that any transparent or semi-transparent wood stain will not 'take' to any areas where any glue residue has seeped out.
This is also true of the alcohol/ink mix also, or any other mineral-based coating.
There are a couple of alternatives:
If you stain with a walnut mineral stain, you can touch up any glue residue spots with an acrylic Gel 'craft stain', in walnut. available from art stores or department stores.Deco Art makes it, maybe Plaid does too.It comes in 2 oz. plastic bottles, and can be thinned with water.
Another alternative is to use a "solid stain", like Olympic or Sears deck stain.This covers well, but you lose the grain...thing is, the grain isn't scale anyway.You thin the solid stain with water to make it easier to apply. If you want weathering, you can highlight the wood with any mineral OR water based paint after it's dry.
I recommend Floquil mineral paint or Polly S water paint for this weathering..you can get greys, browns,etc., and mix to suit.
You can also weather over the solid stain, or the transparent stain with the alcohol/ink mix.
Good luck and regards / Mike
