All is not lost, just polish the part now and degrease and activate and re nickel plate

Hi Mark!

I started to sand the dark spots with 400 grit but I sanded and sanded and sanded and wasn't able to remove all of it. Maybe that's part of my problem?

In the 10% acid solution does it need to stay in there with agitation or just dipped in the solution? Is it then sprayed with distilled water then in the nickel bath?

BTW........how's your plating going on your end?

Steve
