The frame looks great! Can you give me details about the galvanizing process? What type of paint are you using? Can you paint over galvanization? If so what is the prep work? Who did the work on the frame? Was it expensive?

Zack, galvanizing is a tough, durable, highly corrosion resistant plating of, mostly, zinc. It requires clean, bare steel to get a good coating and that is a problem for boxed frames. I had mine sand blasted to get as much clean as possible. When I delivered it to the galvanizers they dipped it in a pickling solution (an acid dip) to remove any unblasted oils and dirt. They got most of it but there are still remnants deep inside which interfered with the plating process.
If only Toyota had dipped the frames when they were new. sigh
After pickling, the frame is completely submerged in a hot galvanizing tank until it is as hot as the molten zinc. When it's lifted out, the zinc runs out of the frame through the ends and bolt holes leaving a noticeably thick layer of plating covering everything inside and out.
To paint over that, it has to be lightly blasted again, which produces highly toxic dust, to rough up the surface enough for paint to stick. My painters used Imron brand paint, applied electrostatically, to paint my frame. Big Cruiser Guy had his frame powder coated but none of my local shops here would touch mine.
I'll have more pictures later.
