Are you saying you can dry sand acrylic latex paint and actually have the
paper cut? *

Not so sure about the acrylic designation. I am not so knoweldgable
about paint. I buy interior latex house paint. The cheaper the better
so it is easier to sand off. Not sure if it makes much difference but
I buy it at Walmart, cheap house brand, cheapest by price I can find
and I assume cheapest in coverage.
