Here is my process to acheive the finish . There are lots of methods, but I like this one for all wood bows. It combines the filling of the grain completely, durability of finish & that depth that only osage seems to have. I would love to finish a house with osage trim, THAT would be cool
1- Final fine sand with 600 grid wet/dry paper.
2- Clean off with denatured alcohol. Use that to check for sander marks & such (there were none!)
3- Two coats of truoil dyed with Alcoholdye stain, applied with the trusty finger. Make sure you get the finish smooth, even & fill the grain as good as possible. Pay attention to the string grooves, tips & edges. Light sand & tack rag between coats.
4- One light coat of clear shellac for a sealer. You can get this in a spray can, but I like to use the airbrush better. Shellac sticks to any finish & can be topcoated with anything. I buff it out after dry with steel wool. Tack rag it off real good after this
5- I then applied 3 coats of gloss Sherwin William catalyzed varnish,light sanding with a 3m fine sanding sponge(sooo handy) & tack rag between coats. I also use a small haidryer to speed up the set up process. It give dust less a chance to settle on the finish. I basically heat the finish up until it sets & let the cats then air dry. I do this on all coats except stain.
6- Repeat step 5 with satin SW catalyzed varnish.
7- It could be called good at this point, but I love this next step. I hand rub rottenstone powder(3fff) & baby oil with a soft cloth to remove any imperfections in the finish, wipe it down with a soft cloth after your done.
8- Next & final step, I heat up briwax or minwax finishing wax & apply it sparingly. I then heat up the wax on the bow a little to dry & let it penetrate the surface. Buff it out with a soft cloth. NOW she glows.
The whole process is harder to write than to do, expecially for a hunt & peck typer guy.
