Is there a specific masking fluid you recommend for Stonehenge Aqua?

We recommend Holbein masking fluid which is not as thick and heavy as other masking fluids and use it very thinly.

One artist we work with suggests using a hair dryer to blow warm air across the surface when they are lightly rubbing it off with a rubber cement pickup.

The warm air releases the small amount away from the paper. this has to be done delicately because the paper is soft and does tend to come up if done to quickly.
