Chinese imitation of P2 spray gun.  Great extra spray gun to avoid loss of income caused by downtime at jobsites.  Alot of the parts on this disposable spray gun are interchangeable with the OEM.  However, several parts are metric and hard to obtain replacements.  Consequently, use this as a spare or disposable gun as the price is cheap enough to pay for itself in 1 job.  You will have made money many times over and can throw it out without any concern when done.
