Rust Shield works best when the metal underneath is clean and completely dry. This kit gives you the full preparation-and-protection system:
500ml / 16.9 fl oz. All Purpose Cleaner: A safe, water-based cleaner designed to cut through grease, grime, and stains on a wide range of hard surfaces. Perfect for boat decks, benches, stainless steel, plastics, concrete, glass, and paintwork. Ideal for prepping surfaces before applying Rust Shield, especially when used with Salt Shift’s hard and soft bristle brushes.
500ml / 16.9 fl oz. Rust Shield: Reliable protection against corrosion. Rust Shield forms a clear, hydrophobic barrier that stops rust from forming or spreading. The oil-based formula cures to a tough, non-stick finish in 3 to 4 days and provides long-lasting protection for vehicles, trailers, and ATVs exposed to salted roads, beaches, and coastal conditions.
Formulated, Made and bottled in Australia.
Approximately 300–350 mL
Tack-dry time: Approximately 2–3 hours
Full dry time: Approximately 2–3 days
Protection duration: Up to 12 months, depending on conditions and use
We suggest checking before each trip to ensure you're protected.
How to check: Rust Shield leaves a hydrophobic barrier on your vehicle's chassis. Once the hydrophobic properties start to fail It's time to reapply.
Pro Tip: If your chassis doesn't rinse clean with a quick wash. Your Rust Shield coating may need topping up.

Rust Shield keeps everything looking brand new! You guys should have a dealer in the United States so we could get the product quicker. It took a month or more to get the Rust Shield on my first order through Amazon. My second order, I went directly through your website and it was slightly faster. Thanks for the great product!!!!!!!!!
Amazing product works and looks great.
Frame looks like it’s freshly painted. Drove through some flood water downtown during a nor’easter at our beach town. Frame had a cloudy look again. Just sprayed it with a pressure washer, water only. Looked brand new again.
Very happy with this works well on my 4 wheel drive we'll definitely buy this again.
Rust shield really works 💪 I've been to the Cape and back with river crossings on the beaches and the dusty tracks etc and everything under the ute is still clean as I love this stuff
Seems to work well, we live Oahu close to the beach so we will see how it holds up in the long run.
Great product. Easy to use, no fuss.
Love it
Amazing product
Works as advertised and the multipurpose cleaner is great on wheels
Easy to apply and if applied correctly there is no running of the product. Also, it was able to do entire under carriage on my vehicle with one bottle. Looks amazing!
Great product
Was a little sceptical but exceeded my expectations with very little effort . Highly recommend
Did my f150 and now my new quad
I like the Salt Shift much better than other undercarriage rust treatment as Salt Shift does not turn everything black. The frame and running gear looks new and it coats without changing the natural colors of the other components. Two thumbs up!
Great product
I’m 55 this year. Was a detailer before my mechanical apprenticeship in the early 90’s. In that time I can tell you of 3 products I would recommend because they work. A particular black RTV silicone. A particular injector cleaner in a bottle. And rust shield from salt shift. I just did the recommended 12 month reapplication and the results are amazing. I almost felt like it didn’t need the top up. Sensational.
Easy to apply. Will get back too you when I’ve done some off road.
Just washed the Jeep, once dried I sprayed the under carriage per the instructions. I did get some on the fenders which are powder coated steel and faded they now look new as does the under side. This stuff just works the only downside is it took 3 days to dry and I attribute that to the humidity but it was definitely worth it!
Excellent product. I would recommend anyone who loves their vehicle to buy this to project your loved vehicle. I would buy this again soon. - Dushan - DK
Easy to use works so good very happy with it . Recommended it to few friends .
Living in the PNW means putting the rig through just about everything—mud, sand, rain, river crossings, and plenty of wet roads. That’s why I’ve been really impressed with Salt Shift. Their products do more than just one thing. They help repel mud and sand from the chassis, make cleanup way easier (most of it blows right off with my blower), and most importantly, help protect the truck from rust and corrosion. The protection lasts for weeks and doesn’t just disappear after a little rain or water. When I’m ready to remove it, I use a chemical wash. I’m pretty picky about what I recommend, especially when it comes to products I use on my own rig. Salt Shift is something I’ll stand behind. Thanks Salt Shift for making a product that actually works. 🤙

Absolutely fantastic brought the entire underneath of my 4x4 to clean and shiny from dirt and road grime Love it and will be using it on all of my cars
Great product
The aging mower trailer has had a rebirth. Cleaned it up and then treated the metal frame and rims with Salt Shift. Should be a good test for this product. It looks good already and hopefully after it has dried will protect trailer for some time.
great products
Very easy to use After I applied the product and was driving with friends.They all asked me why my car looked so good underneath
Was sceptical that it was going to work, 3 weeks on and the chassis is still looking good compared to how it was.
It's great stuff
Stays on really well. I know my chassis is protected. Excellent product
I cleaned it down, then applied salt shift. The attached photo is after a 300klm run up the coast, another day up the beach and wash off. It's still as good as the day I applied it. Love it.
They said it cleans. And it CLEANS!
Very easy to use and leaves a great finish!
I really do believe your product works great. Easy to apply. Seems to last decently from application to application. Time will tell how well it protects from our wintry salt season in Michigan. The price is a little high (even on sale) compared to other barriers that I have used but if it works........ I really like how it hardens after application. Others that I have used collected dust and dirt and had to be forcefully removed with a pressure washers before reapplying .
Perfect and easy to use.
Great, awesome product
Love the brushes ... wheels are easy to clean. Salt shift is excellent for my 4x4 ... I do not do any beach work, however I do spend a lot of time on private properties, so have to contend with mud and manure ... cattle always prefer to leave their droppings on the tracks for reasons only known to them. Highly recommend the products I have purchased from Salt Shift.
This my 2nd order after a year 👌 so it really stays on and works.
