Every "Ceramic" Grill Coating Repels Water -- The Question That Actually Matters Is Whether It Repels Grease

Water beading is the easy half of coating performance. Grease beading is the hard half -- and the only one that matters on a grill. Here is the surface-energy chemistry behind hydrophobic vs oleophobic coatings, and a 60-second oil-drop test you can run on your own grill.
