Automotive Sandblasting Perth
Panels, chassis and full shells taken back to bare metal without warping the steel or filling your shed with grit.
In short
We strip full body shells, panels, chassis, trays and parts back to bare metal without warping them. Water in the abrasive stream carries the heat away, and heat is what causes the oil-canning you get from dry blasting thin panel. Most of our automotive work happens at the customer’s own shed or workshop.
What comes off
Restoration work fails at the prep stage. Filler over rust, paint over filler, and the job comes back in two years. Wet media strips enamel, filler, primer and surface rust in one pass and leaves a profile the new coating can key into.
Water in the media stream keeps the panel cool, so thin steel and alloy do not warp the way they can under dry blasting. We can work on your driveway, in your shed or at your restorer, and we mask glass, trim and rubbers before we start.
Why wet blasting suits panel work
Dry abrasive puts energy into the steel as heat. On a door, a bonnet or a guard, that heat expands the panel locally and it buckles as it cools. Once a panel has oil-canned it does not come back, and no amount of filler hides it properly. Water carries the heat away as the abrasive works.
The second reason is the shed. A dry blast in a home workshop means grit in every tool, drawer and bearing for months. Wet media drops at your feet and sweeps up.
What blasting will reveal
Stripping a shell removes the coating and everything the coating was hiding: previous accident repair, bog laid over rust rather than cut out, patch panels, and rust holes in sills, floor pans and lower guards.
None of that is damage we caused, and finding it is the point of the exercise. Where we uncover something significant we stop and call you before continuing so you can decide how to proceed.
After the blast
Bare steel starts flash rusting quickly in Perth conditions. We apply an inhibitor as standard, but the shell needs to go into epoxy primer promptly. If your painter is booked, tell us the date and we will sequence the blasting to suit. There is more detail in flash rust, explained.
How the job runs
Site look
We check access, water, power and where the spent media will be contained. Free inside the Perth metro area.
Mask and set up
Glass, trim, rubbers, bearings and adjacent panels are protected before the nozzle comes out.
Blast
Wet media at panel-safe pressure, nozzle kept moving, passes to the level of strip you have asked for.
Wash and inspect
Rinse down, flash-rust inhibitor, and handover photos of anything the coating was hiding.
Panel, chassis and brightwork are three different jobs
Thin panel
Doors, bonnets, guards and roof skins are the lightest gauge on the vehicle and the least forgiving. We drop pressure, increase standoff and keep the nozzle at a shallow angle so the abrasive shears the coating rather than hammering the steel. A panel that has already been filled and re-filled is thinner again — we ask before stripping anything that rings hollow.
Chassis, cast and suspension
Rails, cross members, diffs and cast housings take a harder hit and want a deeper profile, because what goes on top is usually a chassis enamel or a two-pack that needs the key. Sealed bearings, bushes, threads and machined faces get masked or plugged first. Cast iron holds contaminant in the grain, so it takes more passes than plate for the same visual result.
Wheels, alloy and brightwork
Aluminium and pot metal do not want a hard garnet cut. Soda or a fine media at low pressure strips paint and oxide without embedding abrasive in the surface or leaving a texture through the new clear. Anodising, chrome and stainless trim are removed or masked rather than blasted. There is more on media choice in our media guide, and on the finish standards in surface profile and standards.

Common questions
Automotive sandblasting — your questions answered
Will sandblasting warp my panels?
No. Water in the media stream carries the heat away, so panel temperature stays low and thin steel does not distort. We also drop the pressure on panel work and keep the nozzle moving rather than dwelling in one spot.
Can you blast a car at my house?
Yes. The rig is fully mobile and self-contained across Perth, so a driveway, carport or shed is enough. We contain and collect the spent media, and we mask glass, trim and rubbers before we start.
How soon do I need to prime it?
Bare steel wants primer the same day in Perth humidity. We apply a flash-rust inhibitor at handover so your painter can start the next morning.
Can you blast aluminium panels without pitting them?
Yes, with the right media. Aluminium is soft enough that a hard garnet at normal pressure will texture it, so alloy panels get soda or a fine abrasive at reduced pressure (see soda blasting vs sandblasting). It strips paint and oxide and leaves the metal flat rather than peened.
What happens to filler and body bog?
It comes off. Wet media removes filler at roughly the same rate as paint, which is why stripping a shell tells you honestly how much bog was in it. Anywhere the filler was hiding rust or a poor repair, you will see it once the panel is bare.
Do you strip the underside and engine bay too?
We can, but it changes the job. Underbody and bay work means more masking, more access work and often removing the drivetrain or suspension first. Tell us at quote stage whether the shell is coming to us stripped or complete.
