I purchased a PreBan AK awhile back that is rusted and pitted BAD.The SN are present and legable but are stamped light.This combined with the rust and pitting has made the Numbers hard to read.This isnt the problem.Problem is Im wanting to Parkerize or but some kind of Bake on coat on it.When I do either Im afraid of what will happen to the SN.SZo what do I do?I want to refinish it but the SN needs to be deeper before I do.Who can restamp or who do I get ahold of to ask????Thanks,45B10
