Mark, Thanks for the info. I have been using oil over unfilled stripped, sanded and stained wood with mixed results. I finally have gotten the desired sheen by using 4-6 coats of oil (tung) instead of 2 or three. On Mahog, pores are the problem. I will try the glue sizing. since I am trying to keep low tech, spraying is not feasible. However I have heard of "padding" shellac, or "padding on shellac". I wonder if anyone knows about this? Is it possible to mix shellac with some kind of oil and rub it on like oil?
