I made a really nice piece using walnut and wanted an oil look finish (satin) with some protection so used Watco oil. I followed the directions: flood coat and wipe off, flood coat and wipe off, and final coat. The sheen was horribly uneven so I assumed that the problem was the wood pores and added more oil. I never could get an even sheen. (everything was sanded to 220). So, I wiped hard with mineral spirits and coated with a seal coat of dewaxed shellac. This was not acceptable either, so I pulled out the sander and sanded back down through the shellac coat and into the oil coat. The sandpaper fouled quickly from the oil, but this was not unexpected. Then I wiped hard with mineral spirits again, and began applying clear wipe on poly. After probably 7 coats of wipe on I have an even high gloss sheen. HOWEVER, I want to get back to satin. What is the best way to do this without having to go back to reapply a finish? Steel wool ()000) is too coarse and scratch marks will most certainly show.
