This morning, I shot an approach in my B55 Baron in moderate to heavy rain to minimums on a precision approach. The water was smearing and streaming on the windscreen. I could not have successfully completed this approach in nighttime conditions due to the obscuration caused by the water. My question is, can a beading agent, such as RainEx, be safely used? “Safe” being defined as not corrosive to the aluminum window frame nor damaging to the stretched acrylic windscreen? I have the “thick” replacement windows installed in this Baron. “In a former life,” I used rain repellent products with LearJets (acrylic) and Falcon (glass) windshields. These products were recommended by the respective OEMs. I would be grateful for any insights you may be able to offer.
