If you have a compressor and sandblaster, use glass bead. If not take Acetone and wipe it down. Then take 800 grit sandpaper and lightly sand the barrel going one direction in an even fashion. If you are super patient and want it done really right, only go one direction not back and forth.I have an old riffle to restore and someone has painted the barrel with what looks like model car paint. can anyone tell me what i can use to remove it without messing up the barrel.
