I bought a cleaning kit some time ago... but a dry kit, not wet... I will upgrading soon to a either a 5D or a Mark II... so I will have to invest in a "wet kit" with swabs etc etc... But Ive heard from some of the newer Nikon owners, that the newer coating will be damaged with the older fluids... Apparently there is a newer type of fluid available for these sensors... I dont use Nikon, but just thought Id mention this.
