Thanks for the link Jack!
Brent, as you can see, searching on Bush and Oil is going to get you something quite different, and not a lot of it pleasant to read.
But this is the stuff I have been using. I have not dealt with Curious Woods, but they look to be local to the manufacturer, who it seems is still working on breaking out of that local niche.
I think the stuff is worth pursuing though. I am not sure if it is linseed oil, tung oil, or something else entirely, but it does a nice job and does it fairly quickly. It is significantly thicker than the Watco I have used in the past, close to some linseed oils I have used. It has been a while so I can't make a real comparison there, but it is thick. One coat is usually good enough, and it dries with minimal bleed out. When I use Watco I can expect to see a lot of little hard shiny spots where the oil seeps back out of the pores while it is drying. Those spots are puddled oil that needs to be removed, usually by a vigorous application of steel wool and elbow grease. This rarely happens with Bush Oil, usually only around a bark inclusion or similar large feature where oil can accumulate.
It buffs up very nicely with a Beall buffing system. I have not yet tried any other finishes over it such as varnish or shellac, but I have done that with success over boiled linseed oil, so I suspect that the results would be the same. Good luck with it!
