View attachment 248039 so I have been tinkering with some cheap cold blue until get sand blast materials figured out. I bought some cheap super blue and attempted a few diff ways of applying until I found what seemed to work best. I like how it turned out. Just not sure how long it will last an stay nice. Also was curious if it’s a the more I put on the longer will hold up or? Below is a pic with 3 coats anyone utilized this coating for a period of time?
