2008 Ford Galaxie Sanding down scratches

Hi, basically I recently hand sanded down a scratch that was on the driver rear side arch, after sanding down I sprayed a coat of clear laquer just once, then to restore the shine I used turtle wax, but it still has that matte feeling to it, I want to restore it back to the paint finish which I think is ocean blue, and also I Have hand sanded a few little scratches, but straight after I used turtle wax three four times, but there is still the same
Dull colour that the sanding left.
