Looking to touch up a few spots and just curious if there is anything like this available?

Not in the traditional sense because parkerizing is a heated process done at 180 deg. F.

Use real parkerizing solution, it's only a few bucks from brownells or midway.

Degrease and dip, it'll park the worn and scratched places, won't be perfect but it'll be OK.

If you can't fit the part in your pot on the stove you can pour it or paint it over the part.

zinc is grey, manganese is the darker park.
