It is.. but If I hope to ever make any money selling these, I can't let one out the door with a flawed finish..
The resin is self leveling to a point.. you can achieve a flat finish by adding more layers of resin... but that is costly..So the smoother and more even the surface is when you start, the better..
This particular type of wood was really thirsty and in some areas the resin disappeared into the grain while there were other areas it stayed as placed..
The end grain of the Elm took a lot of resin
The table I made from Black Walnut took minimal prep to achieve a very nice finish..
