Why Rust Proofing Matters
Underbody rust spreads faster than you think:
- Lowers resale value by thousands
- Weakens structural integrity over time
- Costs more to repair the longer it's left untreated
- Can make your vehicle unsafe
- Kills the aesthetics and visual appeal of your vehicle

What our clients say
Couldn’t be happier with the service provided by these blokes. I took my Land Cruiser troopy in for an undercarriage wash as it was caked with 30 years worth of dried mud- which had set like concrete . The result far surpassed my expectations. They also cleaned the engine bay which looks incredible!
Josh was super helpful in sorting out a rustproofing treatment for a car we were taking abroad. Competitive price, very easy customer experience and timely quality job. Would 100% recommend on demand auto care if you are looking for the services they offer :)
We live 4.5 hrs from Dandenong so taking our vehicle here was huge. We are extremely happy with the outcome of rust removal and repaint. Very professional. The service was top notch and only to happy to accommodate our needs.
After 3 trips to Fraser Island & driving on beaches of SA I found a lot of rust under body. Got the rust treatment, repaint & antirust coating from On Demand Autocare. Very professional and an amazing job done. Highly recommended.
Came in with my 93 swb nh looking a mess, booked in for the full detail, laser and rust protection and I was blown away at the finished result. Car looks like it rolled out the factory floor. I cannot thank these talented guys enough for their work. Job well done!!!
