Seeking test to prove our ECPD works on autos

Dear Sir,

We are manufacturers of Electronic Corrosion protection device used to retard rust on Cars. We are exporting these units to our collaborator.

We intend to launch the product in India and for that we need to convince our customers and satisfy them about the usage. Thus we intend to have a test to see the performance of the unit.

The unit is basically two electronic gadgets supplying free electrons on the body of the car and thus retarding rust. We would like to know from you which test should be conducted so that it is amply clear that the gadgets retard rust on CARS.

Thanking you ,

Put it on a high milage car or taxi in a city that salts the streets heavily in the wintertime. Chicago, IL comes to mind.
