I think it would be good as long as the acid can be properly neutralized.

BTW, my Z28 was primer dipped from the factory. It still rusted.

This is why I like Eastwood anti rust. It's waxy and self heals if it gets scratched. The 2 foot extension wand is good for getting it into hard to reach areas. For sure, the metal that gets a coating won't rust.
