Hello again,
In this month's issue of AOPA Pilot, Dave Hirschman discusses using Rust-Oleum's Never Wet hydrophobic spray. The set up is a two-can pack. To use-apply a base coat, and then wait 30 minutes to apply the final coat. (I would copy and paste the article here, but I am not able to.) He applied this coating to the leading edges of the wings and tail of his RV-4. He let the airplane sit out during a snowfall, and apparently the Never Wet really helps the snow slide off. He also took the airplane flying (there is a video for digital AOPA Pilot subscribers, too) and discussed how the sprayed leading edges were ice free while unprotected areas picked up trace ice. This Never Wet spray is not transparent, so the spray is not suitable for windows/windshields. He of course cautions not to use this a FIKI set up (Flight Into Know Icing), but as a time buying protection for inadvertent ice encounters.
