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 beneath the surface, causing 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 specifically designed to creep and spread .
This is especially important in body cavities , where rust often begins. These areas are often inadequately protected and retain moisture .

💧 Can rust protection spray drip?

Well-developed products minimize dripping . Use only rust protection sprays specifically formulated for this purpose , benefiting from extensive research and development.

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

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