dou_b_14,
As I explained to you in our personal disussion earlier today, your guard must have slipped down somewhere along the line during your swabbing. This is a very unfortunate circumstance, but you jumped the gun and sent your camera to Canon before you reported the problem to me. You didn't even send me a test shot as I requested to have a look at the "scratch". Our protocol that is advertised extensively on our website is to have the customer send the unit to LifePixel for filter replacement. LifePixel will replace the filter and also try to determine the cause of the damage. They'll then return the filter to us here at Copper Hill Images for further testing.
Our ironclad guarantee still applies - if a third party such as LifePixel can conclusively state that the PecPad material that touched the sensor was the SOLE cause of the damage, we will pay for the total cost of the repair. Unfortunately, the course you chose to take will prevent you from ever knowing exactly what caused the scratch, if it indeed was a scratch.
Here are the possible causes of the damage as I see them:
1) The PecPads come out of the pack in an almost sterile state. The only way to contaminate them is to mishandle them somehow before you place one on your sensor.
2) There may have been a particle of some sort sitting on your sensor that you failed to notice before swabbing. Please look on this page for our warning in bold yellow lettering:

3) Using an inordinate amount of down-pressure on the sensor may damage the filter.
As per my e-mail to you earlier today, we feel terrible that you damaged your camera. But we have been around a long time selling the same cleaning kit that you bought. We at no time have ever said that it is impossible to scratch a filter using our method and we even encourage potential customers to examine themselves to determine if they should even attempt self-cleaning a sensor - it's the very first paragraph of our tutorial. Some people should simply use our SensorSweep or just leave it to Canon or Nikon to take care of. In hindsight, you may fall into that category. It's not a perfect world by any means, but we stand behind our products 1,000%.
