You have 3 choices in my opinion.
#1 Take it somewhere and have it done right by a professional and spend more than the gun is worth.
#2 If you're going to bubba it, a can of Krylon works and looks better than a refinsh by someone who doesn't know what he is doing.
#3 Live with it.
Personally I'd choose either #2 or #3 on that rifle. They have a small following, are decent guns, but not worth a lot of money.
