Well my black anodizing lasted 37 years - how bad can it be? sam :-) Original Message From: Bill Coleman via CnC-List Sent: Monday, June 30, 2014 9:07 AM To: cnc-list@cnc-list.com Reply To: Bill Coleman Subject: Re: Stus-List Aluminum coating
I am guessing they stripped the old ones with an acidic process, and it left the surface rough. I would have been better off sanding them all down instead of having them strip them. People in the plating business don't recommend black anodizing, because it does not last near as long as the natural color, which is, well, the natural color of aluminum. What I did do to them, is coat them with PPG Strataclear,(Hard automotive Clear Coat) which I used on the cabintop and areas of the deck not non-skid. This is still holding up well and looks better than as anodized. I think if you used a clear coating on a black paint, you would get much longer life. I also did a test with the Strataclear over varnished teak around my companionway, it is still great after 9 years. I am not sure why I don't do that on all my teak. It just seems too good to be true. . . .

I can confirm that on the feet, there was issue with the baking process. The end result is as if small bubbles of air were burst near the surface of the aluminum, producing a few patches of crater-filled landscape. The defect is very noticeable up close, but since I have reinstalled them I never noticed. When time comes to refinish the stanchions feet, I will avoid powder coating. I was leaning toward re-anodization. Bill, any reason it came out coarse?

Mine has been eroding away in a few spots over the years. Might be best to remove the pedestal and have the whole thing powder coated, but maybe the zinc chromate primer and black paint might get me by for a few year? What do you think?
