Both of the reels mentioned above feature a polyurethane coating, which seems to me (a non-engineer) to be one step down from anodizing, but a big step up from painting. I have some good experience with the polyurethane coating. A few years ago, a saltwater guide friend of mine recommended a Shimano Stradic spinning reel made from magnesium; I was hesitant to buy a magnesium reel for saltwater, but Butch assured me that the polyurethane coating on the Stradic would hold up. It certainly has, over several years now; the reel has given me excellent service. Therefore, I would not be hesitant to buy one of the mentioned reels, given that the manufacturers are so highly reputed (as is Shimano).
