Just wanted to publicly apologize here to Tunghaichuan for my flippant response to this post. After reading about the anodizing process--which, as a chemist by training, I found quite interesting--I thought to myself it wasn't something I'd want to try personally, with all the other projects I have going on. Being in a rush at the time, I posted the single word response of "Pass...".
Though truly not intended that way, it was easily interpreted as rude and dismissive of his idea, which was NOT my purpose! I apologize to Tung for my thoughtless comment (now deleted), and will try to be more sensitive with my wording in the future. My bad, sir!
I know others here share my opinion that Tung has quickly become a highly valued & respected member of this forum with his wealth of knowledge & experience, and unflagging willingness to share it. His informative post deserved a much better response than the one I gave it.
