Flood FLD6 Latex Paint Conditioner, 1-Gallon & FLD6-04_SML FLOOD/PPG FLD6-04 Floetrol Additive (1 Quart) Original Version

This is great to use for fluid art. Make sure you mix well. This is not the AU brand but you can get cells with this. Be careful you can get little boogers after opening it. They also sell a strainer but you can strain it yourself or just be careful pouring.
