7018 should be kept in an oven if not used up completely within 8 or 9 hours as it will draw moisture. also if you don't use large amounts of it buy it in small quanity's so it isn't laying around open for long periods of time.
Wet material, high moisture, and damp rods in the 70 series of welding rods can and does promote and causes what is called HAZ cracks in the root of the weld.
an as you have already indicated not all welding rods of the same type will weld the same way for everyone, the rod I like which will do a wonderful job for me is a rod that you would probably hate, its all in the make up of the flux. I normally hate welding stainless steel specially the E310 series the rods just don't want to cooperate but I used some rod on a job while in Chile on a change out that welding flat was like welding with 7024 the slag would actually curl up as it cooled leaving the prettiest stainless steel weld that I ever saw except for TIG.
