Amazing difference in the before and after pics. I got the same results cleaning the rims of my 70 Scrambler. Went to work on them
with various combinations of ScotchBrite, rags, tooth brush, rubbing compound, Mothers Mag polish. Like your pics, I was surprised how well they came out.
Your sprocket actually looks pretty good compared to how you got it but I can see that maybe a new one might be the cherry on the cake.

EvapoRust is great stuff and I was able to clean up my Rupp wheels with it I bought a gallon of it at Harbor Freight tool. I then powder coated it with Chrome powder coat and sprayed it with automotive grade 2K Spray Max glamor clear coat. The place I did it at said lots of Hot rodders do this with their
old mag wheels since the clear powder coat clear coat ruins the shiny Chrome appearance of the Chrome powder coat and the 2 K spray Max does a great job of protecting the powder coat without destroying the Chrome finish.

if you don't want to use the 2k spray max (it's expensive and once mixed, you have to use the whole can), you can also use 1k Max. it does not mix, and you can use it like any other can of spray paint. And it's $15 a can. Because your hot rod friend is right, as soon as you put the clear powder over the chrome powder, the shiny goes away.
beautiful job on the bike @Brent m your pre build photos reminds me of the JC penney swinger Trail setup minus the Rupp decaling on the engine, they used a numbering system similar to the Black widow on the ID decal. the back of the seat would have been the tell most likely cant tell if any of it remained on your original seat though.
The 2K is a catalyst based and get much physically harder than non catalyst so it will not wear off as easy. Also it is much more UV resistant too and the non-coated Chrome powder coat is not very UV stable so it will break down and discolor if left uncoated. So far the Powder coated Chrome on my Rupp still looks great and it will be nearly 4 years since I did it in Fall of 2019.
I have several years on my chrome powder coat with SEM 1k spray can clear, and it has held up fine. the problem i have with the 2k stuff is the film thickness. you can see it on the pictures he posted above, it looks *thick*. on a gas tank or fender that is fine. but on a rim (or worse, handlebars), it really is not a good thing. you want a thin film covering the chrome powder, and the 2k products are just too much film thickness. this really presents a problem on handlebars, as your controls (throttle mostly) just won't work unless you remove all the material. but on rims and spokes that flex, having that much clear is not a good thing either. you can't add a flex additive to spray can products, so if the clear is too thick, it can spider.
I have even used clear lacquer over chrome powder coat. that even works. you have to use something, because the chrome powder will tarnish quite quickly if you don't use a clear over it. the SEM 1k dries harder than lacquer. but depending on how you're using the bike, either will work.

No not to the “ rupp elite”. Just check back a few months on here you’ll see where I got beat up over it…and the prick that sold it to me ridiculed my nephew so bad about it on a rupp site he quit the site….I will never own or work on a rupp again…just my opinion….
It was a john fellow out of Virginia just in case his ball less ass is in here.

This is what I started with. Who gives a flying arse biscuit. No stickers on mine no proof of authenticity. Its got a souped up Predator 212cc stage 3 goes 57 mph. My wifes nephew I believe his name is wreck it Ralph flipped it over last year and gave it the high impact test on the asphalt. Now I got to fix it.
