I grill almost all of my fish with the skin on because that gives you real protection at least on one side. It's a nice barrier against super high heat which tends to make a lot of fish to turn really flaky. It's very easy to overcook fish on the grill. But I still brush it with oil before I start.

So the way that I avoid this is I keep my gravy - the second it's done, I put it in a thermos, which will keep it hot and will prevent air from getting to the surface. And I keep it there till the last moment. The last thing that goes out to the table is the gravy, and I pour it out of the thermos and immediately move it in.
