I'd be reluctant to do an outside-only coating on 310 stainless. Although it is a low carbon (less than .04%) stainless alloy, it is not high-temp stabilized by Titanium like 321 stainless. It could still suffer from problems with the formation of chromium carbides despite the relatively low carbon content.

Also remember that most stainless steels have less than 1/5th of their room-temperature strength at 1600*F.

I'd look for an inside-and-out coating if I were in your place. Crucial's coating seems to hold up and insulate quite well.
