We are specifically looking for the Spray Guns with Brass Pipe & plastic, If not Stainless steel.  Will it be possible for you to supply the same to us.
 The spray gun will be used to spray BORDEAUX mixture , i.e. a fungicide.( Bordeaux is a mixture of Copper Sulphate + Lime). We use 0.5% of Bordeaux in 200 litres of water with PH  9 to 10.
 
We would like to know whether a scalp formation or chemical reaction will happen with the Aluminium  pipe with Bordeaux mixture.
Please offer the best prices for the same & supply period.
