Actually VHT Nite Shades can be done light and done right.
It does require several coats and plenty of wet sanding with high grit. Put on 2 light coats and let dry, wet sand with 2000 grit gently, go back at it with 2 more light coats and let dry, wet sand with 2000 grit gently again, then put on the clear coat. When the clear coat (if you do 2 or 3 light coats, whatever you do) dries, buff it out. The end result should be a light, even smoke and very glossy.
You DO need clear coat though because as others have said, Nite Shades is a very flat finish.
