Five things you should know before choosing a rust protection spray

🔍Do you already have rust spots on your vehicle?

If so, avoid wax, varnish, or rubber-based products. These trap moisture under the surface, allowing oxidation to continue.
Oil-based rust inhibitors, on the other hand, penetrate through the rust to the intact metal, displacing moisture and oxygen and thus stopping oxidation.

✅ Is 100% coverage possible?

Yes – if you choose a product that has been specifically designed to creep and spread.
This is particularly important in body cavities, where rust often starts. These areas are often inadequately protected and retain moisture.

💧Can rust protection spray drip?

Well-designed products minimize dripping. Only use rust protection sprays that have been specifically manufactured for this purpose in order to benefit from intensive research and development.

⏱️ How long does it take for rust protection spray to dry?

Oil-based sprays remain permanently soft, offer a self-healing surface, and do not chip or crack.
Conventional (hard) underbody protection products should cure within a week.

🛞 Which spray improves the appearance of rusty surfaces?

NHOU® Back N Black, an oil-based rust protection spray, improves the appearance of rusty surfaces and offers the same protection as the clear NH oil variant.
