Hi Len,

I tried an experiment this weekend.

I took a piece of cotton fabrique painted it with a solution of
paint thinner and exterior silicone calking. It dried in a couple of
hour and completely overnight. It is soft and flexible and

I made a thin solution for the first coat, and thicker solution for
the second and third coat.

The underside is not coated, but I suppose it could be.

If you use just one thin coat it is water repellent but you can pool
water on it and squeeze droplets through the cloth.
