Beach Barrier — Stop Rust Before It Starts

🧴 What Is Beach Barrier?

If you’re a beach driver, you already know the problem — salt, sand, and moisture love to

Clean Offroad Beach Barrier Underbody Protection Spray to prevent rust

stick to every inch of your 4WD. Once they settle, corrosion starts fast, especially around chassis rails and underbody components.

Beach Barrier by Clean Offroad is your invisible armour — a spray-on protective coating that stops salt and moisture from bonding to metal surfaces. It’s simple, effective, and built for the harshest coastal conditions.

⚙️ What Beach Barrier Does

Once applied, Beach Barrier forms a thin, hydrophobic layer that:

  • Blocks salt and moisture before corrosion can start
  • Prevents rust on exposed metal and underbody parts
  • Repels salt, sand and grime for easier post-trip cleaning
  • Leaves no greasy residue, safe for paint, rubber, and plastics

Think of it as sunscreen for your 4WD — invisible protection that lasts.

🧽 How to Use Beach Barrier

Clean Offroad Underbody Cleaner rinsing the undercarriage of 4wd

Step 1 — Clean First: Rinse the undercarriage to remove any loose dirt from under your 4wd. This can simply be done with a hose, but for best results, use an Underbody Cleaner attached to a pressure washer. Allow to dry. 

Step 2 — Spray: Spray an even mist directly over the chassis, diff, suspension, cross member, wheel arches etc, and exposed metal areas. Try not to oversaturate — a light, even layer works best. (If a lot of product is dripping onto the ground, you are going a bit too heavy). Avoid spraying onto the exhaust or brakes.

Step 3 — Let It Bond: Apply Beach Barrier at least 24 hours before driving on the beach, to allow the barrier to form.

Step 4 — Reapply: Beach Barrier will last for a minimum of 2 weeks on the beach (allowing for heavy beach driving) but will usually last 6-8 weeks for normal beach use. Top up protection prior to each beach trip.
