I use the MG Chemical positive Resist boards 600 series. I use a glass casarole dish. Right after you put the board in you can see the resist coming off and soon can make out the traces. I use a foam brush to lightly go over the board a few times. If I don't use the foam brush sometimes it may leave a thin film that slows down the etching. Ben
