Downey Street Rustproofing. Over 13 years on the web!

Professional Customer Service

We are talked about across all 4wD forums and blogs for good reason.

We pride ourselves in our ability to serve our customers as best we can.

Complete Rustproof Service

Our complete rustproof service will increase the life of your vehicle and improve resale value.

Using the very best hybrid technologies we have 1000’s of satisfied customers, you can rest easy knowing your vehicle is getting the full service it deserves.

Underbody Rustproof

We all know that pressure washing alone will not remove built up grease and grime.

That’s why we use STEAM – it is the only way to ensure that all grease and grime is removed properly the first time.

After Beach Service

 Our after beach service will ensure that your 4WD will stay rust free.

All salt and sand is removed from the underside of your vehicle. We can take all the hassles and worry away from you when you leave your car with us for its after beach clean.

We are certified distributors of CouplerTec™ the best electronic rust proofing

CouplerTec™ is a major export here on the Gold Coast and Brisbane, Queensland, exporting to USA, Canada, UK and New Zealand. Multi-award winning, multi-international patented CouplerTec™ products have stood the test of time.

Rust is formed when metal looses electrons, oxygen and iron combine to form rust. Paint oxidisation is also caused due to a loss of electrons.

The advanced CouplerTec™ systems pump electrons into the car body to offset the electrons that are lost naturally. This is not harmful to computer systems, people or the car battery; this supply Vs demand ensures oxygen can not combine with the iron to form rust as the supply of electrons offsets the loss.

Well the down side after such a trip is cleaning... After crawling under the Prado, it was caked in sand, in all the nooks and crannies. Chassis rails, bash plates, sills, and I mean everywhere.

Hutch (thanks mate) previously put me on to Downey Street Rustproofing in Geebung. So I booked in there for an "after beach clean". They put the Prado on the hoist and steam cleaned everything under the vehicle, including completely flushing out all the chassis rails, cleaned everywhere in the engine bay, the whole outside and underneath the Prado. Took about an hour and a half with the staff working non-stop... I could not believe the amount of sand and road grime that came out. It is crystal clean now. Great Service. Cost $90. I am not associated with them in any way, just a happy customer. $90 is way worth it in my opinion.

Cheers, Robert.
