(will meld right in)

flammable substances

or use to avoid reflections when a guitar is played under the
intense lights on stage

GENERAL INFORMATION ON NITROCELLULOSE FINISHES:
• standard wood finish traditionnally used by instrument makers
• easy to use
• can easily and rapidly be repaired, even after years
• originally developed by DuPont as an automobile finish, nitrocellulose consists of a clear plastic resin
dissolved in various petroleum distillates
• nitrocellulose dries entirely by evaporation, leaving a thin flexible layer behind
• nitrocellulose requires less training than French polishing
• nitrocellulose accepts a wide variety of transparent dyes, pigments and metallic flakes (Holoflakes!)
• very suitable for touch-ups or finish-blending on high-gloss nitro finishes (low-gloss nitro finishes
are much more difficult to repair)
• nitro finishes are more resistant to body heat and scratches, although they will react to human
perspiration, rubber vinyl pads on guitar stands and vinyl guitar straps
