Technical Paint problem/ help needed

Had the same problem ! It's tree sap from the oak trees to bring in closer another view it's the avids little green bugs there residue is landing on it ! Need to wipe with clean wet paper towel just before yopu spray and come back with a clean dry paper towel . Make sure your tag rag is opened up and hanging a half hour before wiping down as that has been a problem also !

 

Also what has been said about the compressor .drain ,good filter and a line filter before the gun those are cheap !
