Some notes about Tru-Color Paint:
Tru-Color Thinner and Rejuvenator works for both Airbrush-ready and Paintbrush-ready formulas. The Airbrush-ready paint can be brush painted, but it is thin and will require multiple layers to cover well. The Flat colors (brushable line) will not spray well at all. It is not recommended to even attempt to spray them.
Because the bottles are plastic, some solvent may have escaped through evaporation. Fill the bottle with Tru-Color's Thinner or Rejuvenator to just below the bottle's neck and that should be the correct amount of solvent to pigment. Of course experiment to see what works best for you.
Tru-Color Paint is an Acrylic 'hot' paint formula with a combination of Acetone and other media for its base. Ventilation when using this paint is required.
Media Mail shipping is only for books, maps, atlases and DVDs. Paint must ship by First Class Mail (less than 1 lb.) or Priority Mail (less than 1.5 lbs.). An order greater than 1.5 lbs. or containing spray cans will ship USPS Parcel Select (tracked ground service). Total shipping cost can be reduced if paint is ordered separately from Media Mail qualifying items.
