Shawtgun Posted May 28, 2013 Author Share Posted May 28, 2013 Hmmm. What's the best way of repairing light marks from mounting accessories? Quote Link to comment Share on other sites More sharing options...
Scout_21 Posted May 28, 2013 Share Posted May 28, 2013 Hmm...good question. Someone once recommended one of those magic erasers (the white melamine foam ones) and some gun oil afterwards. (http://www.ncgunowners.com/forum/showthread.php?tid=19377) Just keep in mind that the magic eraser are basically a high grit sandpaper and could probably remove the finish if you kept at it too long or pressed to hard... but I don't have any first hand experience with this. Best of luck! Quote Link to comment Share on other sites More sharing options...
