5 amateur gunsmith Posted by mbwebb15@frontier.com on Sep 22nd 2020 Had an old p38 slide dated 1963. Used a scotch brite pad to clean the blue off. Shot it with brake clean. Used paper towel to apply and let it time out. Wiped with paper towel. Rinsed 5 minutes in cold water. Dried it on electric stove burner set on low. Repeat. Gave an even black coat that looked factory with no work this time. Great.
