AP..
I donno if this is suitable cos I've yet to tackle my beech slab, but I kinda stumbled on a dead easy finish the other day working on elm..
I wasn't too happy with how my panels were turning out with just a wipe on coat of Organoil; I was loosing a ton of character in the wood, and yet I wanted to stick with the oil because of it's child safe features. So I played around with it a bit, ending up wet sanding it using 320 grit..
simply poured some oil onto the panels, spread it around some to even the distribution, then started applying the elbow grease through the 320 wet and dry. the dust mixed with the oil to form a kinda slurry that was a perfect colour / compatability match with the wood. The slurry gets drawn into the open pores and acts as a sealer. Once the mix felt sticky (snatching the pad outa my hand) I quit, finishing the job by buffing away the excess with a clean rag and letting the panel dry. I haven't applied a 2nd coat yet, but as they are, the panels feel wayyyyyy smoother / silkier than a simple wipe on coat. The finish is a kinda matt satin that retains most of the character of the bare wood; colour tint is on the honey side of neutral. Looks nice.....
