Undercarriage refresh order of operations

[Corey Bowcutt]

This winter I am removing the undercoating on my 68 GT350 and respraying the red oxide primer.  There are 4 steps to the refinishing as I see it.  The only step I am not 100% sure the order of is the application of the seam sealer.  This is my guess as to the order of operation please let me know if this is correct or not.

1) Spray with red oxide epoxy primer
2) Seam seal
3) Body color overspray
4) rich weld blackout overspay

Thank you, Corey

Yes, that would be the correct order

Red primer? '68s only have that in certain areas like under the engine. Other areas are a batch grey that more closely resembles a mix of GM trunk spray and corrosion? I don't know how you replicate that?

The best illustration of it were the pictures of -00212 that were posted on Forum 1 and got lost in the crash.

The bottoms of my '68, -01107, look just like that. It does not look like the all red oxide like the '67s do.

Good luck with that. I have no idea how you accurately recreate it.

The 1968s I have seen used a reddish brown red oxide primer. I have seen a lot of 1968s and challenge you to post a gray primer car.

+1  . Dearborn cars were typically batch color/gray

What I have seen and collected pictures of. The batch (often a dark gray/ blue or green tint) gray would be what was typically applied to the floors from the firewall rearward on 68 Dearborn cars as Bob wrote

It's not a grey primer it's a rusty/greyish crud. It's only red primer under the front engine bracing.

As ususal, YOU"RE the expert and my car is a bullsh it phoney counterfeit along with Phil's -00212. But that's ok. Everyone knows that YOU know absolutely EVERYTHING about '68s.

You can show us a picture of the plaque that you had engraved for yourself that proves it! 



The color in the vicinity of the bell house is PINK. There are three sections to the color. It changes from front, to center, to rear near the axle where it is the crud color.

Phil's car is almost identical BUT the common denominator is they are both white cars.

[Coralsnake]

Just post your pictures or post Phil's pictures that will solve it.

I never claimed to know everything, but I appreciate the compliments. I think there are going to be a lot of embarrassed 1968 judges.

Personally, I am always willing to learn.

If you would like, I can post some unrestored 1968s?

[Coralsnake]

1480 unrestored looks more red than gray to me?

[Coralsnake]

3660 - before restoration looks red

[Coralsnake]

Unrestored 4114 hmm, this one is red oxide too?

[Coralsnake]

88 looks a little darker, but it could be the lighting. Unrestored white car.
