Topic: 67 Underside resto

[V8_bloke_28]

Hi. I'm restoring the underside of my 67 fastback in which I've taken all the paint off to bare metal.
Before I paint it red oxide, should I paint an undercoat first or is the red oxide good enough to use as an undercoat?
Cheers

A bit more information is needed.

How did you prepare the metal?  If blasting, with what media?  Stripping?  Abrasive sanding?

What type of primer will you be applying? PPG DP40 or...?

Are you after a factory correct look, or something else?

What type of repair work, if any, will you make?  Filling pits, removing dents, cut and replace sections?

As long as it prepped right then the epoxy primer sealer or mixture of that and paints will work as your first and final coat

Why red oxide?   As mentioned above we would need to know when and where the car was built to help guide you to at least what was being applied at that plant - during that time period if you didn't take the time to document what was original on your specific car

You only want to do this once

Hi
The car was built in San Jose in late June 1967.
It has the original red oxide or paint or whatever you call it underneath which I want to freshen up.
I want the same colour as the factory.
I started sanding it to bare metal but I've reverted to soda blasting.
Could I paint the red oxide straight on the bare meal or should I use a primer.
I will fill in some screw holes with body filler that's about as far as repairs will go.
Cheers

Depends on what product your using but if your using a red oxide epoxy primer sealer like Ditzler/PPG you can apply that directly to the bare metal after you have prepared it first. Degrease and such

Straight from the "can"  it will not match your original floor color - that would require tinting to match. Also if your doing the front frame rails and that area the tint can be (often enough to notice) different from the floor section

also i would not fill the screw holes with bondo. weld them up & grind down. it will yield a much better result.
