hi. i just purchased a satajet 90 for $25 dollars from a pawn shop gun looks great but painter left paint in gun so the nozzle was clogged. i tore the gun down and like the old days soaked the gun in aircraft stripper and then cleaned with thinner. will this affect the gaskets in side or should i be prepared to buy a rebuild kit. also is 200 a good price for a sata nr2000 in like new but used condition not clogged with paint lol!!
