I have a 7 year old IG and the ladder and hand rail anchors are all but rotted in to oblivion. I guess aluminum, stainless and salt water just don't play well together. I see that you can buy anchors in bronze or in cycolac plastic (same material as the steps on most pool ladders). My question is which material would be best and is there any suggestions on the best way to replace them in an existing concrete deck short of cutting out and replacing a large section of the deck.
