Beach driving looks epic. But salt air and sand are two of the harshest things your vehicle can encounter. 🌊🚙

A few things to do after a beach trip:
1️⃣ Rinse the undercarriage thoroughly, salt accelerates rust fast
2️⃣ Check your air filter, sand finds its way in
3️⃣ Inspect your brakes, wet sand is surprisingly abrasive

The adventure is worth it. Just give your rig a little love afterward. 🙌

pov: 2001 Mercedes ML320 comes in for premium semi-drying wax undercoating

Old truck, still solid — we’re not letting rust win. Wire brushed and needle scaled the heavy areas, pressure washed, foam degreaser to cut the grime, salt brine neutralized, rust inhibitor first. Then fogged every cavity and frame rail with our Lemmer gun before laying down the semi-drying wax on all exposed metal with the Avanti. This stuff stays flexible for years and keeps creeping into every seam.

Spraying oil based undercoating (Platinum Rust Protection) directly over rust on this rear diff. Before you type the comment — yes I see the rust, yes it’s intentional, no I’m not going to fix it first.

Imported Land Rover Defender 90 from Italy. Tailgate got damaged on the trip over, so before anything else we welded it back up solid. From there, pressure washed the whole underside clean, let it dry, then laid down a premium semi-drying wax for rust protection. Stays slightly tacky so it keeps working into seams and panel gaps instead of just sitting on top like a hard coating would. Welding, washing, waxing — one Defender, ready to go.

Undercoating done right takes more steps than people think. Pressure wash everything down first, knock out any existing rust, lay down a rust inhibitor, fog the cavities so it gets into spots you can’t even see, then the undercoat spray goes on last. Skip a step and you’re just spraying over a problem instead of fixing it.
