Black Oxide Coating

[1969 beep beep]

Hi Guys,

I purchased the black oxide solution from Caswell. I sand blasted some bolts and dipped them. Then sprayed them with WD40. What is the best way to protect them from rusting? The oil coating will only last so long. They look great but for how long?

Learned about this from the Corvette Purists and they swear by it. I use it and couldn't be happier. It provides the best barrier for rust prevention without changing the finish. I performed many test with the products out there through the years. Boeshield lasted 8 days on a piece of bare metal left on the ground before tiny spots appeared.

The next best thing is Cosmoline......but the drawback is it is not clear and has to be removed to expose the metal finishes...

The black coating is iron phosphate. witch doesn't have much protective ability but does provide a rough surface finish that holds oil very well. This is why cosmoline works better than wd40 or oil because it is thicker and is harder to displace from the surface. I have heard of a product called I think it is called RPM that is supposed to protect natural metal finishes and it may work well but I have never tried it.

RPM works very well and once you learn how to apply it, the job is not that difficult to protect your work.

Hi fellas,
I bought a product named "Everbrite" to coat my aluminum engine with and it applied easily and did not change the appearance. No real world testing yet.

Thanks for that info! That product has a wide range of uses and I like the versatility. I am still hesitant using clears on bare steel, mainly due to having no luck with them in the past.

Any chance of getting pics of your engine you used this on?

Oil on anything attracts dirt.

Lol....the majority of restorations utilizing these processes do not drive fast enough to attract dirt...

I haven't used this but it's suppose to be pretty good.

If you want them black just use flat black paint?

I use RPM myself. I media blasted the brake backing plates on my '57 and used RPM on the bare steel. A year later they look like the day I did them. Not a spot of rust.

That said, like 69bfan said, the trick is applying correctly. You need to warm the parts up to allow the product penetrate and buff off the excess (if desired).

Thanks everyone. I am going to order the RPM product tomorrow.

Check out sharkhide. It's expensive, but the results are undeniable.

Remember that from my boating days....Great stuff...I don't recall it changing the metal finish appearance either.

I prefer to use a product that provides the best anti corrosion properties while maintaining the actual metal finish appearance....A tough combination to achieve.....

Thanks Justin,
I worked 7 years after retirement to earn "toy" money for this sort of extravagance! BTW, 765 HP.

That sounds like some kind of Dinitrol derivative.
".....thin, waxy film....."
Or maybe LPS3 which I think smells and looks the same as Dinitrol.
I don't know but every time I see something like that for aircraft use, I think of Dinitrol and have flashbacks.

I have wanted to buy this for my project for a while...have a lot of suspension parts I want to do in a 'natural' finish.
