I'm making a table from Sapele. I stained it using Old Masters wiping oil stain but, unfortunately, due to the grain it came out blotchy. A friend suggested using a dye instead of oil stain. I tried the dye on a sample, and it solves the problem.
I proceeded to sand off the top layer with the oil stain. Unfortunately, no amount of sanding gets the oil removed completely. A few minutes after sanding I observed dots of oil on the surface, apparently coming from deep pores. It has been a few days of sanding and observing the same result.
