If your going for a real good deal, just go catch some park ducks an tie some fishing line to them and toss them out in your spread.
Its a mojo, jerk string, and decoy all in one package.
GHG Pro grade spray some Krylon Matte Finish on them right out of the box and your paint will last a lot longer!
I almost did this but someone told me a while back that it makes them shine pretty bad, so I decided not to. Apparently that's not the case for you?
I sprayed mine down. Birds still come in. I haven't noticed any increase in shine, but the colors seem to stand out better
