Aircraft with bleed air rain removal systems, such as Cessna Citation and Learjet, need to have their windshields treated to help disipate the rain. Repcom rain repellant was the recommended product, but it is no longer available.

Rain-X is manufactured by the same company and it is the same formulation. While not FAA approved, it works well in dispersing water on the windshield.

*Not Recomended for acrylic sheet products, such as, windshields or windows on small general aviation aircraft.
