Make sure when storing your dye the bottles don't tip over. The caps don't seal too well.
Oh yeah, let me throw in another warning or two.
WARNING: Use adequate ventilation during the staining process.
WARNING: Use of a dust mask is highly recommended during any of the sanding stages.
WARNING: Wear gloves during the staining process to prevent skin contact with the leather dye.
Note: As with any chemical, be sure to READ ALL WARNINGS AND CAUTIONS posted on the label.
Note: You may choose to wear leather gloves during sanding to prevent getting any splinters.
"Fast Orange" works real well for cleaning your hands if you get any of the dye on you.
