Who can introduce spray painting? Harbin airbrush generally how much a square meter?

Spray painting is divided into 2 categories:

Ink outdoor spray painting cost in 6-7 yuan / square, printing speed is very fast, the external price is generally about 9-10 yuan, can withstand the wind and rain, clarity is not very high, suitable for far away from seeing.
