The principal reason I can see for your application beading up is most probably due to the fact that you are using too much oil. When dry, this creates a very slippery surface. Again if trying to overlay with oil, assuming you are using the same medium, what allows this layer to adhere to the previous? By incorporating a resin or balsam into your medium, you have added a natural adhesive. (no adhesive then you must compensate with the garlic to ensure the next layer will bind to the previous). I believe all mediums should have a resin or balsam component. Dammar is probably the most popular resin in use today. It
