Thanks!
I stripped all Tru-oil using Denatured alcohol. I then removed the remaining factory finish using 220 grit, followed by finishing sanding with 400 grit. There were still some areas showing sanding marks, so I actually worked up to 2000 grit to gently work out the sanding marks. When sanding was complete, I cleaned off the sanding dust using compressed air, followed by a wipe down with denatured alcohol.
Finish applied was as follows, and in the order listed below;
Minwax Pre-Stain Conditioner
Minwax oil-based gel stain (Walnut)
After this had 24 hours to dry, I then applied Behlen Solar Lux Dye (American Walnut)
Stock was then sealed with 4-5 coats of Maccari's Royal London Oil with 24 hour curing time between each coat
After 4 days of final curing, I buffed the finish using Maccari's Stock Mud to take away the high gloss and to blend the finish
A Protective coat of wood wax applied as a final step
Unfortunately the Behlen Solar Lux Dye is no longer made. I still have a 1/2 bottle of the dye as well as the Reducer and Conditioner. It seems to last forever as not much is used on a gunstock.
