Great work, brother, it's looking great!
Strong point of reference, especially since your visor isn't too close to your face - Go very light with the chroming, and test it as you go the best you can. You'll have to leave it in it's dry state after spraying (no coating, unfortunately, at least as far as I've seen and tried, it makes the chrome non-transparent). The less you put on, the more you'll be able to see. Get to the point where you can see through it in a dark room, but can't see your own face in the mirror, then leave it - it will give you the best results. You can always touch it up if you accidentally touch it later.
