I like using DU-5 as it flows alot better as well.
You can mix concept color 2parts color/2 parts hardner (DU-5)/1 part DT reducer , makes it flow better as this is how I spray it .........Its not the High Solids mix ratio though.
Its pretty hard to get as when its all sold out of the warehouse we will be using DCX61 which i hate.

Are you going to use 2002 clear with the color ?

I dont use the concept clears over my DBU/DBC, as I like the Global clear alot better , plus it doesnt have a solvent pop problem , and it rubs like butter
