Hi Simon,

yes, this is exactly what I've been doing. Sanding in between every few layers to have it flat and lint free. I don't know how many coats I have been adding so far, but it's been almost two(!!!!) small bottles of tru oil so far. Now I know that grain filling with tru oil was a dumb decision, I now know what grain fillers are for, LOL! But I think I have been laying doing 40 or even more coats of tru oil so far. I think a combination of filling and sanding is what's needed, but it's a slow process. To be honest, I don't know if I would use tru oil again. I just don't have the patience to add 2-3 coats a day over the time span of many weeks. Really, that's just not my thing. I need to try the wipe on poly next time.
