I had my fenders powdered. I put dummy/place holder bolts into the rear fender threaded points to make it clear to 'look out for them'. My guy said he was going to put some rubber stops in or something. Anyway, bolts were left in and powdered with fender. I can get an allen into the bolt head on the top side of fender BUT the threaded section of the bolt coming through underneath of the welded on 'nut' is also powdered. How can I get these out? 4 on back side of fender, 2 fender sides. I haven't called him up about it yet.
