Default Black Phosphate oxide coating?? At home kit???

Im ready to recoat a few of the items that came off my 66 BB. IN particular the oil fill cap, 90 degree bend breather tube, half shaft bolts and a few others that were black phosphate from the factory.

Has anybody tried the Metal Blackening system from Eastwood? Should i try it or just send the items to someone for replating/coating

Thanks

I got pretty good results using Eastwood's kit as long as I dilligently followed these steps:

1. Wire wheel as much of the part as possible then wire wheel it again.
2. Bead blast the part to surgical cleanliness and then bead blast again.
3. Do not touch the part until after blackening or the coating will not adhere.
4. Follow the instructions in the kit....quickly dip in the blackener, soak in the sealer, and hang overnight to dry.
5. Drain and blot the part as dry as possible to assist in air drying.

I had no luck at all without the bead blasting step or if I touched the part. If you don't like the results, start over at step 1 or 2!

As a test, I did exactly what tehlers said. Bead blasting, cleaning, following the instructions to the letter. I hung the parts outside, out of direct contact with the spring rain, but still open to the moisture in the air. Within two days, the parts started to rust.

I have a friend that swears by this stuff. It is from a company called Caswell, and all they make is plating products.

I used the Eastwood kit about 15 or 20 years ago with great sucess. You definitely have to clean the parts well. Eastwood changed the chemicals a few years ago (EPA issues I am sure) and I have heard the results are not the same.
