After recently overhauling the finish on the metal work of my air-rifle I had a large amount of bluing cream left so I decided to try it out on other bits of kit. To cut a short story down to size I now have a well blued roll pin buckle on my webbing. I thought I would share the results with ARRSE. I blued the buckle using G96 bluing cream The process is really very simple clean the surface, then apply the cream with a piece of cloth. After you have blued the required surfaces wash the piece off in warm water. 5 minutes max. I purchased the roll pin buckles from Kitmonster and the cream from my local gun shop. I hope this has been informative if a little dull.
