I started with epoxy too, but have switched to Titebond 3. I prefer the no mixing and less waste. Right out of the jug! I am still experimenting with different mediums. The first was corn cob grit that I got from my taxidermist neighbor. He uses it to dry hides and skins in a tumbler. I found it too abrasive. Switched to wood flour and have used that for years. It is maybe a little too fine, as I found I can get heavy handed with paint and it fills the texture too much. Lately I have been working with both Homer Coat, and Harbor Freight Fine, and a combination of each of them with wood flour as the second coat. I am working on 4 sleepers now that will each be a different recipe and will be painted to see which is my going forward process. (can you guess my profession?)
