I always use 3M fiberglass restorer and wax . Keep a spray water bottle handy, keep it wet. I use a 6'' buffer and wool pad, dont put pressure on it and watch your corners. It can burn the fiberglass. It removes the oxidation and leaves a nice shine. You'll feel it get easy when the oxidation is removed, keep misting it with water. Let dry to haze and buff off with a towel. If its heavily oxidized, may take a couple of times.
