Hey, I ended up using that "nightshade" spray on tint -- worked great!
Behold -- before and then after!
BEFORE:
AFTER:
Now it looks jet black from a distance and only up close can you make out the cf weave. Exactly what I wanted
Also, keep in mind that it looks darker both before and after in the pics than it did/does in real life -- rest assured that in real life if you look closely you can easily see the weave.
Anyway, I am pleased
