Looks good! Is your FGY33 in KR5? Mine was, and I liked the color.
I have found progressive wet sanding from 800 to 2500 followed by a compound polish works quite well, but the real key is in the protective UV "wax" that you apply at the very end to help delay the re-haze.

Yep, it's a KR5.

In general, cars of that color aren't very popular, but there seem to be a lot of Y33's rolling around with it.

The Sylvania kit includes "surface activator" in a small spray bottle, 400 grit, 1000 grit and 2000 grit wet-sand paper, a small ketchup packet of "clarifying compound" paste that goes on after all the sanding, and a "UV Block Clear Coat" that you apply with the edge of a paper towel as the final coating.

Takes maybe an hour to do both headlights.

I can't think of any other way you could spend 20 bucks on your Q and get such dramatic results - Makes the vehicle look 15 years younger.
