I am in the process of the this build and the binding glue soaked into the redwood being that it is so porous. When I hit it with Naphtha you can't see the glue marks. the question is will they show up through amber nitro or will the effect be more like it is with the Naphtha applied. Any suggestions would be really appreciated. First time working with Redwood and relatively inexperienced. Also what is good grain filler for Redwood.
