Come up pretty nice I've used Alclad myself in modelling and i like the results it gives. One thing i might add is that you can remove chrome from plastic by placing the part in a bath of caustic soda (mild solution, about 60gm per liter of water) which works very well. You still need to sand back lightly with a fine grit as there is always a slight yellowing left behind. I had my helmet hydro coated with a design and used the method i just mentioned to prepare the part for the process.
