I've been tempted to buy one of those for a couple of years now. I don't really need one. I don't know what I would actually do with one, but they are interesting.
I tried to send you a message with a couple of pictures, but I wasn't able to send them that way. So seeing that this post doesn't really fit the rules, I'll post it here.

Alex, here is the experiment using the Wunderfil. I posted the pics in order so you could view the progress.

1- After initial burn
2- Cleaned with toothbrush
3- Settings I used on my 30w diode laser
4- Result before lacquer
5- Finished item

Hope this helps you out.
