Patrick, you continue to amaze....have you considered Lizard Skin for your coating? Seems to be multipurpose. A question that I didn't see earlier, on your floor/footbox....did you leave a drain provision anywhere for the odd chance that you get caught in a downpour? I was wondering if a weld in bung might take care of that if you continue with the aluminum....won't tear or crack from vibration like a plain hole might.
I finally did notice a small sign of you being a normal motor head though, these are the first pictures I remember where your garage floor wasn't spotless.
Keep 'em coming. ken
