Please use whole words, not leet-speak.
I haven't tried using the sponge technique with photoresist yet, but I
have used it with toner transfer. Do do this, you need to use a
coating film to protect the toner from the abrasion. I use Pulsar's
green film for this. Photoresist should be usable as-is if it's
adhered to the board sufficiently that the sponge won't abrade it off.

No, I'm not the pre-sensitized pcb.
So far, all I've used is toner transfer, or dry film photoresist which
I apply myself. I use Adam's wet lamination technique.
