I'm in the middle of refinishing a Ducks Unlimited o/u 12 gauge for a guy.
He wanted the stainless receiver done in satin brass and the barrels in gun blue.
The receiver is heavily engraved and it rusts in the engraving..which is why he wanted it refinished.
First lesson..smooth steel will look brighter then engraved steel when you are comparing two seperate parts done in the same color...I figured that out after redoing one of the parts 3 times...
Lesson number two..the "brass" bead sites on newer shotguns..aren't brass. They are brass plated and 120 grit aluminum oxide will knock that stuff right off...
Lesson number 3..taking a shortcut to save time is a stupid thing to do. I redid the beads in the satin brass. However..I didn't want to bake the barrels first then bake it again for another hour after I did the bead sites.
So..I let the barrels air dry and masked them off using the green automotive masking tape and sprayed the beads.
Pretty damn proud of myself at this point.
Then I slowly peeled the tape off and left all kinds of adhesive on the barrels...
Lesson number four..know when to turn the compressor off, the lights off and walk away for the night.
