Depending on the viscosity of the sprayed product, a thinner might have to be mixed in (consult product manufacturer for appropriate thinning agent). Some high viscosity products may be too thick to spray through wands. If the product is hard to spray through the wand, shortening the wand might help.

This spray gun is not for use with motor oil or paints.  Cleaning instructions are included.  Does not need to be disassembled to be cleaned.
