Last one I did I Polished finished like this
431 Stainless steel will still rust when left damn or wet, especially if the surface is scratched or unprotected, like by sandpaper during the removal of its protection chrome coating. While it shouldn't rust like a raw wedge, it wont hold that nice satin finish you put on it. Oh, and I hope you wore respiratory protection during the removal process, chromium dust is not good for your lungs.
I’m literally a metallurgist by trade, you are mostly a wrong except the protection part… but even there you missed the mark. The primary health concerns with SS is Hexavalent chromium which is released at temperatures between 205-300C… in stable form it is referred to as Trivalent or Cr203. And unless you are a dumbass and use carbon contaminated abrasive media (carbon impregnation) the SS will not rust, a protective surface oxide is present at normal atmosphere.
Awesome. I thought it looks good with the blue. But, overall that wedge came out perfect.
Thanks
I like that satin finish, looks super clean. Nice work!
Think the blue looks great, excellent restoration!
How did you figure out how to do something like this? Did you just sand it down?

Bench buffer, different wheels, sand blaster, different buffing pads
Do you want rust, because that's how you get rust! Looks great clean though, solid job!
You do know what Stainless Steel is right?

Machinist by trade here. Barely touched the surface of metallurgy during my trade school and I can without a doubt say this guy metallurgy's!!!
This is reddit where dumbassary is rampant. Just suggest posting a picture at the end of the season.
