I can't see the youtube here at work,
but just ran across this instructable:
http://www.instructables.com/id/Sponge-Ferric-Chloride-Method-Etch-Circuit-Bo/

if it's the same,
I apologize,
but thought of here as soon as I saw it.

I saw this for a double sided etch. What do you guys think of this technique?

I don't know but I sure felt like getting up and dancing!!!!

...but seriously - it looks like an interesting way of doing it - might need to subsitute some things here and there.

I would think that you would want to watch the thickness of the board. You need that seam at the top to be aligned on the center axis of the board, or some drift from top/bottom would occur.

This is true, thick boards will cause troubles, but the thickest I ever use is 1/16", so it is not much of an issue.

I use the same method, except I use toner transfer, and tape the two layers together.
