I think the springs are 'painted', not phosphated...

Gary, the hood hinge springs should be manganese (dark) phosphated.

I must have confused my years, Lloyd...  in the fifties, the springs were painted black; the hinges were zinc...    (I shouldn't rely on my memory anymore...  :)  )

Lloyd,

   You are saying manganese with the understanding of the difference between zinc (phosphate) vs. manganese solutions, correct? If so then I now have a use for the unopened bottles of manganese parkerizing solution!

Thanks,
Mike

Hi, some of the posts refer to component finish charts. Where do I find these? I am doing a partial restoration of my 1968 Z28 and something like that would be nice!

Thanks, Mike! Would this be also correct for a "68"?

 I believe it is valid up to '69.

I should have asked Lloyd where his information re 'phosphated/manganesed' hood springs came from?  I've been doing a little digging to clarify my own memory and I find no reference that specifies to phosphate or manganese any springs.  Not even the list from McNeish's book as provided in the reference states that, but it does specify for the hood latch spring that it be black painted.   I did find several references that heating, acid dipping, or phosphating a spring can cause hydrogen embrittlement, and in extreme cases totally remove the 'spring' from the spring...

Does anyone have any additional reference on this subject (in particular, hood spring coating or treatment?)...

 This link does show springs dark. Black paint or manganese? If the spring was painted I would think it would not fully cover the surface area between the coils when not installed and I'm not sure if the factory would bother to place them in a jig to separate the coils.

If you are in the Dayton Ohio area bring them by and I can do the hinges and latch assembly.  I have 10 gallons of the Palmetto stuff mixed up.
Only local stuff.  I don't want to deal with shipping etc.  Glass bead it ahead of time.  I use a SS single bowl sink on the barbeque grill.  It works great!
Thanks for the most generous offer, but Ohio is too far to travel! But I would have brought the beverages and the brats!

Agree somewhat Lloyd and you may be 100% correct but from my perspective they were not but service replacements were. Every service replacement reviewed including a set I had from 1979 was a dark manganese, almost a light black but survivors including our 69 Nova are just a dark gray phosphate. But again you many be correct friend. Great talking to you and reviewing items at MCACN Lloyd. :)
Opps, me bad as we are talking about springs. My original springs were not dark manganese.

Chick,

  Were your hood springs still phosphate finished even though you removed them from the hinges?

Mike

Mike, no they were not! I took them off and used evaporust to lightly remove some surface rust, protected with rust preventative and placed back on the hinges. I think it also looks much better as they should have two different looking finishes instead of being both phosphate with the same stuff.

These were my spings Mike after a little tender loving care and just before replacing on hinges. Never any trace of paint and they look now as they did before minus a little surface rust.

Chick,

  Your springs are raw steel then?
