Chuck,
It wasn't me saying to use 3 min, we use 4 and it works fine. Very difficult to overexpose RapidMask.

David,
How close do you hold the nozzle from the media? You might want to try 6" and back off on the pressure.

David,
I tried blasting these with 33psi as recommended by Photobrasive. When I turned the pressure down to 27psi, I got a much nicer etch.....

Probably nothing but the standard inaccuracy of the pressure gage. Minor wear in the nozzle or venturi mixing area can make large differences also.
