Same for me here on tru oil. Works good to seal up. I then also use a satin spray polyurethane or the like. I like this one it dries pretty hard and seem pretty clear. Worked good for me over the tru oil on hide too. Here’s one I did earlier this year on a yew bow. I just used a small paint brush and use fiebings alcohol based leather dye. Let it dry really well before putting your finishing coats on as the leather dye will effect the drying of your finishes. FYI.
