Water Pickup

We're they painted or were they anodized. Anodize fades in the sun like I'm seeing there, and it won't let ammonia or a mind acid react with the zinc. I am seeing a white chaulking corrosion in the c/s holes. That crack looks like the plates saw some trauma and hole to hole was the weak link.
It's kinda funny my old hardware on my boat half of was made with 7075. There's a lot of chaulking on some of the parts. Kinda like these old boat builders were just that and racers on the side. Seems like they would just go down to the local material supplier and grab all the rems of aluminum that were available. Because aluminum is aluminum , right?

I figured it was paint because it didn't cover the edges in the middle. I also sanded an area down and rechecked with the ammonia, no color change. There was definitely a lot of flex going on where they cracked, the doubler has metal transfer from rubbing and a small crack forming as well. The new plates will be 6061 T6 if that is what is prefered these days. I even considered going to stainless since the pedal will have some type of assist on it for racing.

That's because who ever made the plate tried to use a single plate and found out they couldn't get the boat to handle for shit and cut the plate in half.
