I had the exact same problem with my 10 month old Wake Design Racks!
I talk to the customer support girl and even the president, he tried to tell me that it was because I lived in Southern California and it was the salt air. My boat has never been in salt water and has never been close to the ocean. I asked him why I didn't have this sort of pitting on every other chrome part on my boat, he had no answer.
A 6 month warranty on this type of product is a clear statement about their quality control. Plus they had some stupid rule that you had to return the warranty card filled out or the warranty was void. Who ever fills out those warranty cards?
Wake Designs will NOT stand behind their products!!!
Hit me up with a PM if you want his name and phone number
