How were factory original dual pulleys painted??

[odcics2]

Sprayed?  Dipped?

Nobody knows?

I know they were semi gloss black.  But as for how they were painted I don't know for sure.

Anyone restore an engine to original, and found out the answer ?

Most originals Ive seen have a very thin coat of paint on them. Looks to have rusted very qiuckly so Id hazard a guess to say they were sprayed.

I powder coated mine

I have a vintage double groove crank pulley for a race hemi that is powder coated. The plan is to strip that stuff off and go back to period correct.
Being it has deep double grooves, it appears it would be tough to get paint in there, hence the question if they just dipped them.

Logically, it appears they did.

My honest opinion is that most part like these were dipped in a paint pool.
I have an original California license place that shows evidence of it being dipped.
Ill upload a pic to hopefully show this to you.

Take a look at this picture.
Hopefully you can see the streak marks of the dripping paint on the license plate going towards the top-right portion of the plate (bottom of the screen).
All of the paint streak marks seems to collect at this part of the license place and drip off from there.
Additionally, the entire plate is covered (front & back) with paint with the same evidence.
This is proof that license plate manufacturing back in the 60's were dipped.

It wouldnt surprise me to see that any other manufactured auto part was painted in the same manner.
SO if you want to do a date correct paint job on some parts, you should probably dip them in paint.

Good info. I 'think' I remember something like that back in the day, when original stuff was still plentiful.
A power steering pump comes to mind. Had drips of paint dried on it.
