Many thanks ,David - great help. I've managed to get the test piece exposed and strangely enough ,it was the same side of the protector that came off each time. With the board exposed, the other protective layer decided to part company. And that was the end with the highest exposure,( I decided on four slots of approx 35secs ) ,divided into four parts of the board, so perhaps I may increase the exposure time by another 35sec.
