I have several new old G3 magazines that I would like to teflon coat myself at home..I have heard brownells makes a home teflon kit and would like to know if any one has used this for your 20rounders...or..pls provide an alternative kit that is recomended...or..should I just say the heck with it and send em out to somebody who is well established in this area..I would like to do it myself if that is possible..so any help would be highly appreciated..thanx
