ive used both CG light clay with CG pro detailer and ive also used CG clayblock with CG pro detailer
ive also used meg's smooth surface clay kit
the CG products cleaned better IMO
CG light clay bar was better than the block IMO
so if your sold on the block .. use like normal clay bar .. but after a few wipes with the block, i suggest spraying down the "clay" portion of the block with your QD to remove what you just clayed off the car
