There was a dent in the back of the neck, but i managed to get it out with steam (I used a damp cloth and an iron).
There were some parts on the body with a very deep grain. I tried to take pictures of it, but the light was not that good and the pictures don't show it.
I sanded it until my arm fell off, but it remained in some parts.
Is there a way I can fill it? Will it affect the staining process?
