The thinner the mix, the less air is suspended, and the smaller the remaining bubbles will be. I gradually added more mineral spirits while mixing fairly sparingly. Once the bubbles were completely gone, I let the mix sit for about 24 hours, and a good bit of the mineral spirits rose to the surface. I poured off the excess, dunked the nylon, and removed the excess with a squeeze, then a sponge. A single treatment made it completely waterproof, even under pressure.
