DIY guy. I read your posts. I understand what you are doing and asking.
I am in full support of your activity. (Educating yourself and Preparing for Possible Anodizing).
It is true, that some do not read, some do not approve, some spend too much time in a vat.
I am a universal Fix-It DIY'er as well. I was told on my Home Inspection forum, that I should not buy a Thermal Imager, but instead, hire a professional.
Life is short, exciting and dangerous. It best to live it to the fullest, for there may be no tomorrow. The lord determines our time and place.
