The finish on these components will last for MANY years, my customers are testament to that. Many engines that I blasted over 10 years ago still look exactly the same. None of these parts are polished, simply blasted, I have many imitators who will say they do the same finish, but their photos show this is not true.
You will find many more albums and pics on the Facebook site than the basic website !
