I've been using Quat for over 15 years. There are different grades for lack of a better term and what Wayne is sighting sounds like surface sanitizer. What you need to look for is dish sanitizer for 3 compartment dish sinks. The tablets kind of sound like what your looking for but just never heard of it.
200ppm Quat is sufficient for general no rinse surface sanitation, but word on the street it is deadly to head retention. Most (including Will Kemper) do not recommend its use for anything that will come in contact with the beer.
