I have both in my hot section. Although I can't easily inspect it due to the wrapping, it has been in operation since 2011 and has over 1800 hours on it without showing any signs of leakage.

I am not sure that painting the SS parts is a good idea. Stainless rusts by a process called "Crevice Corrosion", which requires the absence of air to get started. Painting would seal off the surface, allowing saltwater to get under the paint at any scratch and begin corrosion.
