This is a 100ml can of Tamiya PS-31 Smoke Lexan Spray Paint. These spray paints were developed especially for decorating transparent polycarbonate bodies used in R/C car modeling. Each can contains 100ml (3oz) of paint, which is the appropriate amount for finishing one 1/10 scale model.
Painting polycarbonate bodies is done from the inside of the body shell as opposed to the outside of a traditional plastic model. When spraying body from the inside, keep the can about 30cm from the surface. After curing apply another coat as necessary. These paints are impervious to oil and fuels, so they can be safely used on gas-powered R/C bodies.
Warning: Never use these paints on plastic models.
