It worked well in spite of the seepage. As long as I wear gloves and work in a glass baking dish I think it will be standard operating procedure in my shop! I picked the board out of the bag with forceps and placed it on a paper towel to dry off the etchant. Very little waste, very easy cleanup. It is simple to examine the etching through the bag while it is in progress.
A side note: I used HP Presentation paper and soaked it off with warm water. It did not separate from the toner at all. I carefully peeled it off and lightly scrubbed it off with a nail brush. Enough of the paper stuck to the toner to give it a frosted look. It probably aided the process.
