I've been applying pink teflon tape since I read about it from Sabotloader.Finding the correct tightnes to wrap with became key.Be sure to start at rear of plug an work forward,overlapping about one third to one quarter.I also use just aLITTLE slick 50 around the tape for ease of plug installation.I agree with Sabotloader that my blow back all but vanished.The seal is so much better it seems.I also no longer back plug out every 6-8 shots as I once did.Have had zero trouble with seized plugs since going this route.Give it a try.Works great for me.BTW,..I use in an Omega and a KRB7.Hopeing to help ya,...hunt4me
