Correct paint for inner fender?

What’s the correct way to paint this area?

1969 convertible

This has great info for 1970 Dearborn cars. Late 69s would be close to the same. I just did my 70 CJ Cougar in Eastwood Chassis Black Semi gloss. I did not follow how the factory did it. But I think it looks good.

Here’s what we are going with.

This is my friend Kerry’s 68, very similar to 69. Factory was a blend of body color, red oxide, and black. Then 3M body shutz applied once

the splash shields were installed.

1970 cougar

I ended up going outside the box and use herculiner on the outside of the them and gloss black on the inside…
