In early '64 I was having predictable problems landing a Gnat on the 6000 ft wet slippery runway, with a x wind, at Rissy. My Antipodean instructor (B R) thought that bellowing at me was going to help - it didn't. Anybody remember a resurfacing involving some lethal-when-wet material called "Slick Slurry"? It was like oily glass when damp or wet.
