Vellox was recommended to me years ago. It is classified as a hydrophobic coating. Here is one source:
I tried cooking spray 30 years ago on the bottom half of an 8' solid dish. What a mess.

Haven't tried it personally, but yes, it should work. Some engineers use stuff like Rain-X with good results too though I doubt it lasts anywhere near as long. All those coatings eventually need to be reapplied.

Has anyone ever tried Neverwet?
I think it would work for a while but what happens over time?
