Whispering Ground

what kind of paper You are using with masking fluid? i've so far tried watercolor paper (ehm, no, bad idea) and drawing paper (kind of architecture students are using; better, but also, not quite good). at the moment i am waiting for the 3rd kind of paper to dry (glossy), so i could add drawing ink.
my problem with Color&Co masking fluid is that when i am removing it afterwards, the paper scratches and rolls off too and it was not once. so, i have no idea, what i am doing wrong. wetting paper with ink to much maybe? will try to wait longer, to be sure it's really, really dry, before removing the fluid.
i like the idea, but just can't get the result i want .
it would be really helpful, if , let's say, the color change could indicate, when the masking fluid is really dry and one can add colors.
the worst thing in this sad story of mine is that i am to represent this product to the group of kindergarten teachers on the 'morrow, 'cause my colleague cached cold, and there is no way to ask, what she was doing / using exactly :/
