Tough call, Ever!

I'm a bit more inclined towards Alclad, because from experience it always gives a good result. With this application you are "pushing the envelope" a bit.

I'm inclined to think that the Tamiya product may be a bit "heavy" for a visor. Alclad tends to be used at very low pressure (airbrush only) and very lightly, so misting onto the visor (from the back?) until you're happy sounds like the right approach. The Tamiya would have to be decanted (else it's going to be like hitting the visor with a fire extinguisher), and I have no idea what the paint thickness (opacity) will be like.

Good luck
