Couplertec Rustproofing System?

[#Russ#Es#]

Just wondering if anyone has heard anything good about Couplertec?

http://www.couplertec.com.au/product/carsystems.html

...its an electronic rustproofing system. After reading the info on their website, it seems like it would work (in theory), and seems to be worth installing (especially on older cars). Price starts at $299 for a self fit kit.

So, does anyone have one/knows of someone who has one, and do they actually work??
