A quick google search brought up these pages
an pretty thorough online review at intscalemodeller.com/viewtopic.php
and the product/company page at http://www.umpretail.com/
this stuff looks like it is THE answer, to me,,,,,,,as does the cleaner
note, that reviewer did test Tamiya and Gunze Aqueous, and gives a thinner/paint ratio in his charts
I am going to take the plunge on these two products, and the Badger Primer mentioned here on FSM,,,,,,,it would be great to cut down to just three products for all these needs from the Chemistry Set I have collected so far.
