megs #80 speed glaze. it has diminishing abrasives that break down during use. it will remove scratches and swirls with a p/c 7424 and not harm the paint. then use some poorboy's black hole(specially formulated for dark color paints) and hand apply to entire car. leave for a couple hours to bond and wipe off with a microfiber. then use a good sealant like megs and then pure carnuba wax
