Got my 4" '61 Python back from Colts today. They did one heck of a job and totally exceeded my already high expectations. I believe a new hand may have been fitted as well because the timing is now perfect and she has a new like feel to the trigger, not a heavier pull or anything worse than when I sent it in, just new feeling. Right away I carefully wiped the gun down with a cotton flannel rag with a few drops of CLP to clean off the oil Colt put on it. The polishing job, everything was spectacular and I now have a new 45 year old Python with old grips. Have to get better looking grips! How soon would I be able to use a Carnuba based firearms wax on it to protect it? I've just seen a new product by Flitz which claims to be safe on blued firearms and contains no abrasive agents. Anyone tried it?
