Hi Sam
Mate I wasn't disputing anything you wrote My post was to tell those that had a dull outcome on their anodising that all is not lost. Simply polish your dull finish and a good outcome should be the result. The better method you wrote about is great news for everyone and I would like you to post which company you use. I've just had a bunch of anodising done by a long established firm. The new items came out superb but the used items were as dull as a Mills and Boon novel.
Mark, I've sent you a few items and I think you will be happy with the finish
