Wow that looks great James.

Here's a few more pics showing better detail of the result. These pics show the bolts still wet with Boeshield on them.

I wonder, was there some order the stamping occurred?  Was the car inspected in a certain sequence?

All three inspectors (Body, Paint and Trim Shop) were stationed at the end of the Fisher Trim Shop, just prior to the point where the body was shipped "through the wall" to Chevrolet; they worked independently.

John,  We all really appreciate your information and perspective, and I have a couple of questions concerned these 'marks' (understanding that I owned my car for over 30 yrs and never *saw* them, until getting on this camaro list.. Smiley..
1)  Why do some cars have the P T B on both side and and some only one one?
2)  Why do some cars have multiple stamps on one side of the car?  ie. My car had two T stamps... (one down below the trim tab)..
If you don't know of a specific reason for the above, I'd appreciate your 'best guess'...?

Gary

Hey Gary my car had 2 Green "T" stamps on the drivers side and possibly a red "B". Those were the only remnants I found on my car. Not sure if the other letters faded away or wore off, of if that is all there ever was on the firewall. From what I am reading so far however it sounds like all cars got all of the stamps. Also note that some cars had both colour stamps on different letters, which seems to be a much rarer occurrence, that all one colour.

Luke and I decided to have a Phosphate Party tonight and we invited some of our favourite fasteners to attend. Check it outů

Step One

Organize glass beaded parts.



Step Two

Fill a pot with water and bring to a boil. We used a hot plate and it brought the water to perfect temperature in about 15 minutes.



Step Three

Then add the Parkerizing Solution to the water. We just did a batch of dark Manganese tonight. Next we will do Zink, the lighter grey colour.





Step Four

Once the temperature is around 190 Ferinhieght it is time to drop the precious parts into the magic solution.



Step Five

Here Luke cradles the virgin, freshly blasted metal. All the kids into the pool.



Step Six

We left the parts in the solution for 15 minutes then removed them and Luke sprayed them with Boeshield.



Step Seven

Then we let the parts dry for a few minutes.



Step Eight

Next Luke touches up a few parts that were a bit dry with Boeshield.



Step Nine

The final product. Enjoy the fruits of your labour. Wonderful, glistening, freshly phosphated original parts. What could be more exciting than that?

Well my car only has the green on it, luckily nobody ever thought to " clean " up the engine compartment . But you can see the B was a lot more crisp than the P or the T.

The stamps I have look nothing like the originals when you compare them side by side. I am trying to find out if there is a supplier out there that makes a more accurate stamp.

I decided to do some test stamps today. However before I started I decided to clean up the stamps to see if I could yield a better result.

Here is the stamp before I worked on it. You can see all of the excess rubber around the B.



First I drilled out the holes in the B with a 3/16 drill. Here you can see the holes drilled in the B & The P.



Next I trimmed the excess material around the cut out Letters with a razor blade.



Then I tried a few test stamps with some latex paint and a piece of plywood. Not an ideal situation, but enough to indicate if I am going in the right direction. As you can see I used a foam brush to apply the paint to the stamps. I found that the key is to apply the least amount of paint possible. Next time I will try an even smaller foam brush and thinner paint on a metal surface. That should give me a better idea of how close I can get to what I am looking for.



The test turned out ok overall. The second one from the bottom was the first test and the driest. I also pressed the lightest on that stamp. The harder you press the more distorted the stamp will be. The rubber stamp is fairly firm, but the black rubber underneath the clear rubber is very soft and compresses quite easily.

Great info. Going to try it tomorrow night. Will post the results.

1969 Camaro SS 396

Just curious if the Blue D90 stripe was a factory special order stripe or added to match the 715 interior. Looks great IMO. Can't go wrong with the Cortez Combo!

Not exactly sure but the rear tail panel is also blue.  The sign in front of the car says that its has the "Nickey" package, so maybe this was done at the dealer before it was sold???

Didn't see the rear tail pan picture.

I am no expert, but all of the 7's posted in this thread so far look to be the same to me. With Consistent tail curve.

JohnZ over the years has mentioned many times here and on other forums print spec's gave the supplier either option but since the clear zinc was cheaper that is what suppliers mostly used. This was before what we know now about cad plating.

Hey Chick what do we know about cad plating now?
Health/Cancer issue!

Are you referring to the plating process itself? What is the difference in health risk between Cad and Zink? Sorry I am new to this. Perhaps I should google it. Both processes are still in use correct?
I ain't no doctor Mike LOL Smiley but yes both processes are still in use. Cad producing shops are mostly used by the aeronautical and military sectors. Due to health concerns with cancer I believe those shops are closely monitored (OSHA).  We did not have any cad in any mfg. plants I worked in so NO expert here......

Thanks Chick I will follow up on it. Always good to be well informed if there are any hazards in our hobby.
