Sorry Pablo, I should have emphasised that comment. His technique for applying stain is stupid in my opinion. You could have the best quality paper towel, but when it's wet, it's going to break down, and in several of his videos, you can see the paper towel tearing apart and leaving scraps in the finish.
I don't have anything against him as a Luthier, I have no experience in that field. But I started looking at his videos in a less positive way after seeing that.
