Prepare a 0.2% solution of ninhydrin in M-butanol and add 3 ml of acetic acid spray the plate and then heat it in an oven at 100°C-110°C... 

An improved salt spray test employed a mixture of sodium chloride and acetic acid. A solution containing 50 g/L of sodium chloride in distilled water is adjusted to a pH value between 3.2 and 3.4 (electrometric) with glacial acetic acid. The solution is sprayed through a small aperture atomizing nozzle and mixed with a compressed air stream. The solution usually is heated to 95 to 100°F (35 to 38°C). Failure under this test is assessed visually, and results generally are obtained within 48 to 72 h, depending on the coating system. 

D) Spraying solution. A solution of 0-2 g. of ninhydrin in a mixture of 99 ml. of redistilled n-butanol and i ml. of glacial acetic acid.
