I've got a Polished watchcase (black seal) that I want to brush.
I got one of those brusing pens from The Watch Boys, but as far as I understand, the area has to be "pre-Burshed" before you can use the pen.
How do I do the pre burshing? I've got a dremel, if anyone could point me to the right direction on what dremel-head to use, that would be nice! Or any other way of doing it.
Btw. the fibers of that brushing pen seem to be very dangerous... I've already had 3 fibers stuck in my thumb, dont wanna imagine what happens if your breath in them fibers.
