Blue is now available in an aerosol spray. The dye used in the aerosol is the same fine dye sold in the dry powdered form in the dyes section. The color will range from medium blue to navy depending on the number of passes sprayed. The dye shows the grain of the wood and is an excellent choice for maple or figured alder and ash. There is no lacquer in the aerosol and as such must be clear coated.
