Solvent left in the spray gun air passages could result in a poor quality paint finish. Do not use any cleaning method which may allow solvent into the spray gun air passages. Do not expose air regulators and gauges to solvent as damage may occur.

Cleaning Process

2.Refer to your fluid source manual for removal and cleaning.

3.To retain unused material or temporarily store mixed material, see your Local, State, Federal and OSHA guidelines, along with material manufacturer’s recommendations for storage.
