Electronic Rust Proofing

Rust Free are the approved installers for Couplertec Electronic Units. After intensive market research and independent testing of the range of electronic units available, it was apparent that the Couplertec units are the best available and the only units Rust Free are prepared to offer to their customers. The product performance and warranty backing of the Couplertec units made them stand above others in quality and rust protection. For personal choice for our customers we felt we should offer both conventional spray and electronic rust proofing. For those vehicles which are not mainly garaged or are exposed to the coastal environment we know that the Couplertec can protect in the roof area, under the rubbers and around the window frames where it is not possible to spray.
For customers who do not keep vehicles for more than three years the Couplertec Electronic units can be transferred from one vehicle to the next.

How it Works

The Couplertec unit runs off the battery system of your vehicle by a method called capacitive coupling. A DC voltage (negative charge) is pulsated through all metal surfaces forming an excess field of ION's. This protective field inhibits the formation of rust and oxidation.
