Diamond Tek


Diamond Tek is the oldest remaining rustproofing business in Australia, having been in existence for more than 35 years. In that time, we grown our reputation of being “second to none” in the automotive industry.

Diamond Tek is a complete vehicle protection package specifically designed as an upmarket product. It has been developed exclusively for dealerships. Their specialist application technicians have been trained in the correct application of all our products.

The unquestionable quality of products and service has, unlike many aftermarket companies, been its primary focus throughout its lifetime and, as a result, it has developed an exemplary and untarnished reputation in its marketplace.

All products have proven themselves well beyond their warranty periods. They have been tested and used in some of the harshest climatic areas in Australia, including Cairns (31 years) and Darwin (25 years).

Contact Diamond Tek for all your car protection requirements for Fabric, Leather & Vinyl and Paint Protection, Rustproofing and Dealership Solutions.

“My car is now 5 years old, but it looks brand new. I got the Paint Protection and it is a breeze to clean. I love it.”

“I go out bush quite often so I wanted to get a good rust proofing system on my car. The NECCS is amazing. It has protected my car so well, and i have never had a problem with it.”


David Mullineux

“I got the full package as I use my car a lot on boat ramps and at the beach. I can’t believe how good my car still looks. There are no water stains on the seats, no marks on the paint, it’s so easy to clean.”
