Oil spray, undercoating and cavity wax for cars that live through Maritime winters — worked into the seams, rockers and frame rails where road salt hides.

Oil film
A thin, creeping oil that wicks into seams and pushes moisture out. It is the layer salt meets first — renewed every fall.
When to book
Spray before the first salt.
Oil works best on clean, dry steel, ahead of the trucks that salt the roads from December to March. Most of our customers book once, every fall — and we send the reminder.
Sep – Nov
Spray season: oil on, before the first salt.
Dec – Mar
Salt season: the roads are white with it.
Apr – May
Spring wash: salt off, touch-ups on.
Services
Every seam. Every winter.
Prices in Canadian dollars before HST, for most cars; trucks and SUVs are a little more and we say so first. Every visit starts on the hoist, with photos.
Yearly oil spray
A drip-type oil sprayed into doors, rockers, seams and frame rails, where it creeps into every joint. Cars $149, trucks and SUVs $179.
From $149 · About an hour
No-drip oil spray
A thicker, wax-based oil that stays off the driveway and still seals the seams. Good for cars that sleep in a garage.
From $189 · About an hour
Rubberised undercoat
A tough, sound-deadening coat for wheel wells and floor pans on newer cars — sprayed only on clean, sound steel, never over rust.
From $399 · Half a day
Cavity wax
Wax fogged inside rockers, doors and pillars through the factory drain holes, where a spray alone can’t reach.
From $249 · About 2 hours
Brake & fuel lines
Scaled brake lines and rusted fuel lines replaced in coated steel or copper-nickel, bled and pressure-tested.
From $380 · Same day
Rocker & arch repair
Rust cut out, new steel welded in, sealed and painted — and then protected, so it doesn’t come back.
From $650 a side · 2–3 days
Underbody wash & check
A hot underbody wash to take the salt off in spring, with photos of anything starting. Free with every spray.
$59 · About 30 minutes
Not sure what it needs?
Book a spray and we’ll look first. Every visit starts with photos of the underside and an honest word about what you can leave for next year.

Brake and fuel lines flake, and the rocker seam starts to swell.
Sprayed every fall: the seams stay sealed, the lines stay black and the arch lip stays smooth — a little surface bloom where stones hit, if anything.

Grew up in a body shop in Shediac watching salt eat cars. Marc opened Saltguard in 2012 to stop it earlier, and still checks every car on the hoist.

Eleven Maritime winters and my rockers are still solid. I book every October and they text me the photos before I’ve finished my coffee.
They showed me a brake line that was flaking and let me decide. No pressure — the spray alone was what I came for, and it was an hour.
I went with the no-drip because the car sleeps in the garage. Not a spot on the floor, and the underside still looks new.
Bought a used truck and brought it straight here. Danny walked me under it, showed me what to watch and sprayed every inch.

Questions
Good questions, straight answers.
Will it drip on my driveway?
A little, for a day or two — that is the oil working its way into the seams. Park on gravel or a sheet of cardboard the first night, and we wipe the sills before you go. Or choose the no-drip oil.
Is it too late if my car already has rust?
No. Oil slows rust that has started and keeps it from spreading. We show you photos of any spot that needs repair, with a price — nothing is fixed without your yes.
When is the best time to spray?
Early fall, before the first salt — September to November. The oil works best on clean, dry steel ahead of winter. Spring is for washing the salt off and touching up.
Is it safe on rubber, plastic and wiring?
Yes. We use an oil made for underbodies that is safe on rubber bushings, plastic and wiring, and we keep it off the brakes and the exhaust.
Will it affect my factory rust warranty?
No. We spray through the factory drain holes and plugs — no new holes drilled — and record every visit on your invoice.
How long does a spray take?
About an hour on the hoist, wash included. Wait in the lounge, or drop the car the night before and pick it up after work.
Do you spray trucks and SUVs?
Yes — frame rails, box and tailgate included, for $179. We’ll quote anything bigger before we start.
