While most of us are familiar with parkerizing and blued gun finishes, I find all the proprietary finishes very confusing. We find names like Melonite, black oxide, tenifer, KimPro, Armory Kote, Ion Bond, it goes on and on. I have read, in regards to Glock pistols, that if you remove the black finish on their slides, the tenifer would still be intact? A resident metallurgist might be able to clear up the confusion. What's best, what should be avoided? Thanks!
