Yellow Zinc plating

[NITRO450EXP]

Hello,

I am about to go down the rabbit hole again.

This time it is zinc plating and yellow dichromate finishing.

I have a pair of 40DCOE32 side draft carbs I am redoing.

I can buy new zinc plated hardware and banjo fittings and linkages, but the stuff on the carbs is original and just tatty.

So tarnish removal and re-plating it is with a nice iridescent yellow finish.

Plus it's only chemistry and who doesn't love chemistry. 

Before pic for starters.

Body has been simple green degreaser and soda blasted, ultrasonic next.

Progress will be posted.

I think it looks amazing! And I am learning something new because of your concerns: https://en.wikipedia.org/wiki/Passivation_(chemistry)

Wow! That's an impressive project. I've got a set of  4 48IDAs that could use that kind of sparkle the next rebuild. Thanks for detailing the process.
