Gabe,

I have been so busy, no time to reply to your previous Q's yet.

For others I think the below link will explain a few things. Apologies if this information is very basic to some, but then I have not really seen the information out there in the gun community.

None of the above provide all the info, but give some background. Not all applies to gun stock finishes, but with some background info we can start to understand what we need from a traditional gun stock finish.
