Common Underside Myths

“You only need to clean your underside once”

​

False Dirt, salt, and moisture constantly build up underneath your car, especially on Scottish roads.

Even a freshly coated car starts collecting grime again within weeks.

​

That build-up traps water against metal and slowly breaks down protection layers.

​

Think of it like servicing your engine — it needs upkeep, not a one-off clean.

​

Regular underside maintenance keeps coatings effective and corrosion away.

“Rust Stops On Its Own”

​

Once corrosion begins, it never stops spreading unless it’s treated.

​

Even if it looks dry or “stable”, oxidation continues beneath the surface.

Moisture and oxygen feed the process — every damp day makes it worse.

​

Left alone, small patches spread into structure-threatening corrosion.

​

The only fix is to remove or neutralise the rust, then seal it off completely.

“Underseal Fixes Everything”

​

It doesn’t — underseal only protects what’s already clean and solid.

​

When applied over dirt or rust, it seals in moisture and accelerates decay.

​

We often strip cars that look spotless underneath — until the coating comes off.

Old coatings crack, peel, and trap water right where it shouldn’t be.

​

Proper prep makes all the difference — clean metal first, then quality protection.

Proper Prep & Coating = Lasting Protection

​

There’s no shortcut to doing it right — we always start with a full inspection and deep clean.

​

Depending on condition, we’ll treat rust, apply primer, add stonechip or sealant, then finish with Lanoguard or a corrosion inhibitor.

​

Each layer has a job: treat, protect, seal, preserve.

That’s why our results last through Scottish winters — not just one season.

Clean. Treated. Protected. That’s how you stop rust for good.
