CouplerTec Electronic Rustproofing

To Whom is May Concern:

Mac's Engineering have now been installing CouplerTec Electronic Rust Proofing Systems to the majority of BMA Coal mining vehicles for the past 7 years to date there are in excess of 2000 of these mining vehicles that have enjoyed protection against corrosion from the highly corrosive sulphur in the coal.

In my opion these vehicles are returning a higher resale value after their stint at the coal mines. CouplerTec have even had happy customers who have purchased these vehicles comment on the lack of corrosion found on their vehicles, this can be credited to these vehicles having CouplerTec Electronic Rust Proofing

If Couplertec Electronic Rust Proofing Systems are this effective in a corrosive enviroment, we believe these systems would benefit all 4WD owners.
