My bro has just started a business in Guernsey wet-blasting manky old engines for everything from Bugattis to Z900s. The engine below was from an ancient Z9, results speak for themselves.
The machine is a Vapormatt Lynx, uses plastic/glass beads, zinc oxide, ball bearings, etc in a solution. Guess who's Superlight is going to have a very shiny engine!
