Sheen of front spoiler

I am fixing some road rash on the front spoiler and need to determine what to pick in term of paint, obviously the lower section is black, what is the sheen? Semi-flat, satin, semi-gloss?

Thanks for the feedback, I also decided to do some (unscientific) testing..

Satin by Krylon appears shinier than stock, is that the general experience?
Semi-gloss is too shiny (Dupli-color)
Semi-flat by Krylon is - to quote Goldilocks "just right"...however, as of two weeks ago Krylon has discontinued the formulation. Back to Satin, probably will be easier to clean and maintain!

 

I have have a couple of cans of Duplicolor Trim black - i'll shoot it tonight and post results.

I will depend on the condition of your spoiler. I did not remove the bumper, however; I have a lift so access is pretty easy. If your spoiler is in poor shape you may need to reinforce, Auto parts stores sell fiberglass kits that include glass and resin. If not structural, bondo will work for the smaller crack and kitty hair (bondo with chopped FB) for bigger stuff. I m not a big fan of glazing putty, as I would rather shoot a couple thicker primer coats and check for problems.

If you have hairline cracks showing that is usually b/c the gel coat cracking below the paint - hard to fix right without major work (ie sand down and recoat). In lieu of that hassle, I have had good luck with a primer that is designed for fiberglass, fills holes and cracks well, good adhesion and flex. You will need to buy it from paint store and shoot it with a gun (tell you are painting a Corvette and they will give yo the right stuff). If you do not have a compressor, gun etc... or are not too picky, you can build up with normal sandable primer (Krylon has one) and wet sand with 600 prior to final coat. It will not hold up as well on the long run but I doubt anyone will notice.
