APW has a good reputation, but I haven't seen any feedback from people who have gotten the Ceraguard finish. If I were you, I'd look into EGW's E Treat finish. Do a search here and at 1911forum.com and you'll find info. It's so new that there isn't any long term experience. I have a customized Kimber getting the E Treat finish now and one of the reasons I went with it was the endorsement and info provided by George Smith of EGW. His reputation and expertise are unquestioned and I figure if he was backing it, it was worth a try.
