I read in another thread that using the etching compound does not work all that well for some reason. Their guess was maybe the compound did not make a rough enough surface. After reading that I decided to use a pointed stone on my dremel turned on medium with moderate pressure and made the scratches kinda deep. Don't look all that good, its only random spirals but it works.
