Like many of you I'm dealing with a lot of rust. I've spent a lot of time reading about how to remove them and prevent them. For hardware (bolts, nuts, etc...) I considered zinc, nickel coating and tried both. Zinc is cheaper and I can tell that the part is getting plated. With nickel I couldn't tell. Also yellow Zinc plating is how the hw of the car originally came with. The plating kits that are out there are just way too expensive to try out so I decided to do the plating on the cheap, and buy the yellow Chromate from Caswell (it's <$40 for just the solution, it's not included in the kit anyways). This is what I have:
- power supply + alligator clips (from
amazon for ~$70, needed this for other things)
- Zinc strips for roofing (quite cheap on
amazon)
- lots of vinegar (from Costco for $4)
- Salt
- lots of distiller water
- yellow Chromate (~$40)
- black Chromate ($40)
When you plate zinc what you get is a very dull looking, non-smooth surface, but it can be polished very easily with steel wool as Zinc is a soft metal. Here is an example, it's part of the center arm kit that I bought, which of course came un-plated and just greased. I would hate to see rust on new parts in a few weeks so I plated it:
It's polished in seconds:
The feel of Zinc is just different to the touch even polished, so I've learned quickly to be able to tell that it's there. This is another piece polished, it's the pitman arm of the steering box:
and then dipped in yellow Chromate:
I ended up painting the above part just because I don't wanna take it apart. So I have layers of rust encapsulator + paint that has Zinc plating underneath, pretty sure it won't rust for a while...
I am Zinc plating all the spindles as well, pretty much anything that I think will rust. I disliked very much taking rusty pieces apart and had to wrestle with the pitman arms so I'd like to avoid that again. Here is the end result:
And even applied a clear coat to some to make them prettier, they look much nicer in person:
I think this solution works for me vs sending parts to get plated. I am taking my time to do things, fixing one piece at a time so I won't be able to send batches to get plated. Overall very happy with the result, but it did take quite a bit of work and trial/error.
