Am I crazy for doing this on a 65 Barracuda ?

I just made a chrome sticker for the centers of the wheels. 3 of them still had the factory aluminum disc but they were messed up. I thought the chrome looked better with the lugs .
While I had the front wheels off I removed the rear splash shield and cleaned out that area and treated it. Couldn't believe the amount of stuff in there. Metal was good and solid yet.
Scraped the loose undercoat off the shield,sanded and treated it and the hardware. 1/2 in bolt broke off but I had another clip nut and bolt.
Good enough at this point to just treat this stuff and put it back on. The front splash shield is mising on this side. I have some and will be getting back into this area . Also didn't replace narrow wetherstrips on edges of shiels. Top rubber seals look good. Even if I don't get back in here, it's not that big of deal as far as preserving what's here. If the crap isn't allowed to build up in there it won't be a problem.
It'll come back off very easily next time .
