Cheers. If I'm French polishing it on, I'm not sure why I think I need to knock it back much, anyway. I have some 2500 grit... according to research that's a lot less abrasive than the oft-used 0000 so might use that lightly every so often on these test oieces. I'm anticipating 15-ish thin coats going on the people who have kindly shared their experience on here over the years. When I finish this plank I might have to bolt a neck onto is and string it up!
