Some notes about Tru-Color Paint:
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. The fumes are not as strong as the former Floquil line of paints.
Tru-Color's 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) may spray with a mix of 40-50% thinner but success is not guaranteed.
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.
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) or UPS Ground. Total shipping cost can be reduced if paint is ordered separately from Media Mail qualifying items.
