Tell me, what effect did the Glaze have?
I have a black car as well. Is it noticable difference in the depth of black?
Given the age/mileage on my car, I know I will not be able to get the black paint "perfect" regardless of how much polishing I do; so the glaze adds a little wetness and "pop" by leveling out the last remaining hints of swirls. Then the FMJ adds the final protection and maintains the gloss. At least that's the rationale going on in my head about it. So just how noticeable the addition of the glaze is, I can't really say; but it seems like it to me.
Give it a try and let me know what YOU think. It goes on/off extremely easily so I'd say it's worth a try for you.
