Trim paint for valence, spoiler...?, Use SEM Black? Options

[retrofit]

Thinking about using some SEM Trim Black for the side valence, spoiler and rear valence. Prbably use it single stage with out clear coat as it has a satin finish. Is there a satin clear coat available? My paint supply shop said only glossy clear.
Have heard of using lacquer thinner in place of reducer will yield a satin/semigloss finish(?) with some paints, but I wonder about the effect on clear coat.

Whoever told you using laquer thinner will yield a semi-gloss finish has been drinking too much laquer thinner ! YES there is a semi gloss clear.I have used it quite a few times repairing mid-late 90's Mercedes bumpers. Next time you're next to one look at the bumper cover. In addition to buying semi gloss clear, you can also buy a flattening agent and add that to regular clear. That is in fact all you get when you buy the semi gloss in a can, and you pay a little extra for it (IMG:style_emoticons/default/dry.gif)
