Tool needed is the spary gun and Air compressor
NO.1 and NO.2 is NOT GOOD for sparing the coating agent/liquid
NO.3 is the best tool for sparing the coating agent/liquid
About the spary gun, the smaller diameter(the nozzle), the better
About the Air compressor, 1~2L is enough (or a little bigger)
How to spary ?
Adjust the aperture of the spray gun a bit smaller, and increase the air pressure a bit, sweeply spray 3 to 4 times evenly. So, it will need less than 1 mintue to dry usually and it will dry very fast after printing and will not fade from color
