But when Good conducted experiments that simulate the method in his laboratory at UB, he found that the company's claims about its product were false.

"It looks like an authentic corrosion-control product," said Good, explaining that the claims sound plausible because the product is described as providing what is known as cathodic protection, and the product includes something that could be called a cathode, which is a negatively charged electrode.

"What makes it a fraud is that some of the parts essential to a cathodic system aren't present," he said.

The electrochemical system is designed to look similar to one that works very well in reducing corrosion in ships and ocean locks, he explained. The difference, he adds, is that when a ship's hull is submerged, the sodium and chloride ions in the salt water conduct electricity, creating a complete circuit.

i wonder why a respected chain of auto stores would sell a sham product.
