I'm guessing cheap stainless, I've seen rusty stainless before.
I think it’s time to weld the Louvers in like Dave did.

Those are not Stainless steel. They are Chinesium.
Make sure the next set is 300 grade Stainless. I am sure those are 400 grade with high cadmium. Prone to rusting. Yep, Stainless does rust.
Put these washers on the bolts. They are an AN style. Small outside diameter. Should prevent the paint chipping. And if you install them curved side down, would be better for the paint. Even though I like them curved side up for aesthetics. I am sure you can find a smaller quantity somewhere.
That’s probably not the hardware corroding, but the exposed steel under them. Hardware has a way of messing up the paint under it, so it’s likely just light corrosion “blooming” up to the button head. If the button head is anything other than 300 series, it’ll also eventually corrode. 18-8 is pretty common, and unfortunately pretty cheap, too.
Also, weld it only if you want to do a ton of block sanding.

Good work. I still wouldn't want to lift a 40 regularly to get access to the back but if your lifting mechanism has the stones to make it easier on the back it should be better.
I had my "little" spare on a swing down and I got to hate lifting the 35" tire up but it had no mechanism to aid in the process.
Yours is already more thought out than mine was.
I'm really hoping for either a pneumatic lift assist or some sort of spring loaded cable spool like a garage door would have, but no matter what it ends up with I may eventually borrow from your design when I get to putting more money into my truck haha
Looks good.
Not to be a dream crusher, but I don't know if I'm 100% behind your lift assist idea. Seems like a lot of work to haul around the jack, board, and stands. Plus you have to get them out with the tire carrier in the way.
Yes, that was tongue in cheek.
You are going to need wheels on that stand if you plan on driving it.
