My rusty cowl repair so far...

Rusty cowls.
Ticking time bombs.
I'm doing one. The bottom was caught in time.
But I putting a new top on because it was cheesy anyway.
For the remaining rust, I'd suggest Rustoleum Rusty Metal Primer.
What are you thinking to use?

I'm using rustoleum rust reformer. I really like this stuff it coverts the rust and leaves a durable black primer finish ready to be painted over.
