I use Birchwood Casey. Reason being, when I had just bought the p365 and I started reading about the early rusting issues on the finish, some members on a Facebook group that work outdoors in Swampy Louisiana used the stuff and their finishes remained great. https://www.amazon.com/Birchwood-Casey-Barricade-Protection-aerosol/dp/B004I9MFHU
