Paint metal parts under playfield, What do you think?

I was cleaning all the parts of my TZ and when I got to the solenoids, I found that some metal parts are about to get rusted or that the original plating is off.
This is what I tried, I clean them in my Ultrasonic cleaner, rinse them, let them dry, apply a coat of primer then I spray them with this: http://www.amazon.com/dp/B000Z8DGXK/ref=twister_B00JC1WIP8
I attached some pics. Look way better in person, pics came out kind of blurry.

I like it but I'm not 100% sure about painting. The other way would be to re plating all the parts.

What you guys think?

Anything metallic like you used will transfer silver to your hands even when dry. That type of paint does not hold up well IMO.

I powder coated the brackets on my afm.

I was actually researching on that, do you think it will be better?
Do you know if the old plating has to be removed first?

I saw your pics in another thread and it looks awesome.
I was also researching about powder coating, they sell a cheap kit at harbor freight.
But honestly, I rather have them looking original.

If you paint them I would use a primer called Self Etching Primer. It "eats" into the metal and seals it not just sit on the surface like regular primer. Then paint with a High Heat paint. I just did this with 3 lock bar receivers and it works great. The home powder coat kit looks like fun to try.

I did use the self etching primer from rustoleum.

wow.... you all must have a lot of time to worry about minutia.
clear lacquer can also protect. But......I guess that's not original....

You are totally right, I just tried with one of the parts that I painted more that 24 hours ago and it did actually got my fingers silver.
I think I'm going with the Home Made Zinc Plating, Powder coating seems like too much work.

Yes.

Silver paint is for huffers.

You can etch off all the old zinc if you want perfectly smooth plating.

Caswell makes a home plating kit. Keep in mind that the materials are caustic.

How are people disposing of the plating solution?

The electrolyte is just Epsom Salts and Vinegar.

If they feds break into your home for having a chemistry lab, drink the stuff and latter take a monster dump.

It does have Zn sulfate and if you are stripping parts you are using HCl. As a chemist I have no issue using this stuff but i also understand the importance of disposing of stuff properly.

How would you dispose the Zn sulfate properly?
