« on: February 21, 2021, 01:28:50 PM »
Is there a product or method that will remove the black stuff from the shield with out damage to the original finish ?  Thanks, Brian

There was not finish on that part, it was bare steel. You can neutralize the corrosion, but it will likely return

Brian is that surface pitted also?  If so your better off just replacing with one that does not have the damage IMHO

interesting.  I've seen this black stuff before.  Usually a part of the general rust/corrosion package.  It's a surface situation that can be chipped/scraped off with a utility knife.  I have heard and read that ' bare steel ' is the usual and was a bit surprised at the appearance of this shield.  I had not though of replacing.  I didn't know that was an option ?  This shield may have been a replacement ?  Part is new to me and is for a C5AW-C Daytona pinion support.  It does have a yellow dab on the side.  Thanks for the help.

OK a bit more cleaning.  Appears to be all steel.  Thanks, Brian

Much improved. Of course if the light pitting makes a difference a swap is possible as mentioned. Just have to get a better one

The stamped steel shield is simply pressed on. You can find a better one from a cheaper application and swap that part easily.
