I would be careful with trying Rain-X. Rain-X is a silanol treatment that is not durable. That is why you need to reapply it on a windshield many times. Also you could contaminate the paste as it will come off the stencil during the printing. From

Has anybody else tried using stencils coated with Nano ProTek? I did find that I could reduce my cleaning frequency and squeegee pressure, which should help to increase stencil life, but I'm finding that it seems to wear off quicker than I thought i
