BYD Shark 6 Tub Protection: Liners, Mats, Covers & Tailgate Guards (2026)
The BYD Shark 6 leaves the factory with a spray-on tub coating — but it's a thin, paint-like finish built for looks and light scratch resistance, not for dropped tools, sliding loads or the Australian sun. Left as-is, the tub scuffs, chips and fades faster than most owners expect.
The fix is cheap and layered: a rubber tub mat for impact, a tonneau cover for weather and UV, and a tailgate protector for the loading edge. Here's how each one works and what actually fits the Shark 6.
- Rubber tub mat over the factory liner — soaks up impact from tools and cargo
- Tonneau cover — keeps water and UV out of the tub
- Tailgate protector — stops the top edge chipping when you load
Why the Factory Spray-On Liner Isn't Enough
The Shark 6's factory tub finish is a spray-on coating, not a thick drop-in liner. It's essentially a tough paint — good for looks and light scuffs, but limited where it counts:
- No real impact protection — a dropped hammer or a heavy toolbox corner can chip it and dent the steel underneath
- UV fade — in harsh Australian sun the coating can chalk and dull over time
- Tie-down wear — strap friction at the anchor points wears through the coating, exposing metal to moisture
- Sidewall chips — cargo sliding on a hard stop gouges the thin finish
None of that means the factory liner is bad — it just isn't a load-floor. That's the job a rubber mat and a cover do.
Tub Mat vs Professional Spray-In Liner
When the factory coating isn't enough, the two main aftermarket paths are a drop-in rubber mat or a thick professional spray-in liner. It comes down to budget, use and permanence.
- Best impact absorption for the money
- Removable for cleaning the tub
- Shark 6-specific mats suit the factory liner or a naked tub
- Roughly $150–450, easy DIY
- Thicker, seamless, permanent coating
- Long service life once applied well
- Dearer (roughly $800–1,200) and not removable
- Can trap moisture and rust if prep is poor
For most owners the hybrid approach wins: keep the factory liner for scratch resistance and add a rubber mat for the impact protection it lacks. A Shark 6-specific ribbed rubber mat drops straight in and can be trimmed for a snug fit.
Tonneau Covers: Weather & UV Protection
A mat protects the floor from impact; a tonneau cover protects the whole tub from the elements. It keeps water from pooling around tie-downs and scratches (which is where rust starts), and shades the tub and any liner from UV.
For the Shark 6 you've got several styles — your pick often depends on whether you run the factory sports bar:
| Cover type | Rough cost (AU$) | Best for |
|---|---|---|
| Soft clip-on / roll-up | $400–700 | Affordable, no-drill, full bed access |
| Hard folding lid | $900–1,500 | Security, supports some load |
| Retractable / electric roller | $1,500+ | Security and a clean OEM look |
Most soft covers clamp to the factory mounting points with no drilling. If you run the sports bar, check the cover is the sports-bar version or needs brackets for a weather-tight seal.
Tailgate & Rear Edge Protection
The tailgate is the most abused part of any tub. The top edge chips and scratches every time cargo drags over it — and it's one of the cheapest problems to prevent.
- Rubber tailgate protector (~$45–80) — a stick-on buffer along the top edge that takes the wear instead of your paint
- Mat that covers the tailgate — extends impact protection to the inner tailgate face where items drag out
- Rear corner care — heavy items sliding out on unloading gouge the rear panels; a mat lip helps
Off-Road: Underbody Protection
If you take the Shark 6 off the bitumen, tub damage often comes with underbody hits — a rock that dents the tub from below can just as easily catch something critical underneath.
The factory guards are light plastic, made for splash and aerodynamics, not rock strikes. If you're doing real off-road work, a Shark 6-specific bash plate / underbody guard is the upgrade that protects the battery pack and driveline. Fit one made for the Shark 6's mounting points — not a plate adapted from another model, which won't line up or protect the right areas.
Fitting a Drop-In Tub Mat (DIY)
It's a straightforward job for an immediate jump in impact protection:
- Clean the tub — degrease the factory liner to strip wax, silicone and manufacturing residue, then rinse and dry fully so anything you stick down bonds.
- Test-fit — unroll the mat and check clearance around the tie-down anchors and tailgate latch; trim the edges with a sharp knife if needed.
- Secure it — heavy-duty double-sided strips at the corners stop the mat shifting when you slide cargo.
- Keep drainage clear — make sure the mat's channels let water escape so none sits underneath.
After a few hundred kilometres, re-check the tie-down anchors — vibration can loosen them slightly.
Common Failure Modes — and How to Avoid Them
- Pick a mat with proper drainage channels
- Degrease and dry before sticking anything down
- Add a few corner fasteners for heavy-duty use
- Prep thoroughly before any spray-in liner
- Trapping water under a poorly-fitted mat — it rusts the floor
- Relying on adhesive alone in extreme heat
- A spray-in over a badly-prepped surface — it peels
- Ignoring the sports-bar seal on a tonneau (leaks)
The most common issue with a mat is trapped moisture — water gets underneath, sits against the floor, and starts rust. A mat with real drainage and a proper fit prevents it.
Check the tie-down points every few thousand kilometres too; strap friction can still wear a liner over time even with protection in place.

Frequently Asked Questions
Does the BYD Shark 6 come with factory tub protection?
Yes — a factory spray-on tub coating. It's a thin, paint-like finish that gives scratch resistance but little impact protection, which is why most owners add a rubber mat and a cover.
Can I put a drop-in mat over the spray-on liner?
Absolutely — it's the recommended combo. The factory liner handles light scratches and corrosion resistance; the rubber mat adds the impact absorption to stop dents. Shark 6 mats are made to suit a spray-on liner or a naked tub.
Is a spray-in liner better than a drop-in mat?
It depends. A professional spray-in is thicker, seamless and permanent, but dearer (roughly $800+). A drop-in rubber mat gives better impact absorption, is removable, and is the best value for most owners at around $150–450.
What tonneau cover fits the Shark 6 with a sports bar?
Soft clip-on, hard folding and roller covers are all made for the Shark 6, in naked-tub and sports-bar versions. If you run the factory sports bar, choose the sports-bar version or one with the right brackets for a weather-tight seal.
How do I stop the tailgate top edge chipping?
Fit a stick-on rubber tailgate protector (around $45–80). It sits along the top edge and takes the wear from cargo dragging over it, instead of your paint — one of the cheapest bits of tub protection you can add.
Do I need underbody protection too?
Only if you go off-road or work on rough sites. A mat protects inside the tub; a Shark 6-specific bash plate protects the underside and components like the battery pack from rock strikes. Use one made for the Shark 6, not adapted from another model.
