Brian,
I used it years ago. Clean the board with a brillo pad then
rinse and blot the board with a towel.(don't touch it with your
fingers!) Do not use paper towels. Stand the board up on end in the
dark and use a red light used in developing to see. Spray the board
evenly from top to bottom. Lay the board flat then use and old hair
dryer to dry the board. (still in the dark, and then put the board in
tinfoil or a light tight box. The thing I found is you need to shake
the can before using. I also found the board needs more exposure and
developing time than the instructions. I suspect my kit was old.

John
