Gold fo' the hunnies...

It's the name of today's Chemistry lesson.

Start off with a bunch of hours of work prepping up some old Z32 rear uprights to make them look all nice and new like so:

Then get you some battery acid, Alodine 1201 and safety gear.... and end up with this:

The sun washes out the color a bit,and it's got quite a bit of green iridescent stuff going on, but it does look pretty baller in real life. They've got a good gold coloration to them. As they've sat out during the day/night they've gotten a little more blue iridescent in them. It's like a ricer paintjob x eleventy billion - but with some fighter jet badass chemistry.


For those of you that are still with me and asking WTF is going on, and why the uprights look like that. Alodine is a commercial name(also known as Iridite) for a chromium conversion process. It's basically a fancy way of saying it's a way to bond chromium to aluminum to prevent corrosion. It also helps paint adhere to aluminum since it won't oxidize beneath the paint(which is why paint flakes off on aluminum). It's used in all sorts of aerospace applications, but they're trying to go away from it due to the chromium content - hence the safety precautions if you use this.

My uprights are now ready for some spherical bearing lovin', and will be corrosion proof for years to come. Goes along nicely with a 100% rust free chassis.

Chemistry FTW!

Cool.

hmm, it would be cool to do my timing cover like that... but eh, im not much for chemistry...

cool stuff tho

Yea the pictures probably dont do it any justice. It just looks durrrrrty to me. Pretty interesting though!

It's not supposed to be cosmetic thing. It's supposed to give a slightly dull gold color, which ranges from light light gold to tan, and sometimes it can be iridescent.

The main reason why I did it is the uprights were in poor shape when I got them, and once I cleaned them up I wasn't looking forward to them being heavily corroded in a year or so.

I'll snap some pics after they get full spherical bearings.
