BUT, can't just polish/buff scratches at home as it will need to handle by the paint shop.
Warp is a option and avg shop charge around $2.5~3K. However, to match factory quality top warp installer charge up to $7~8K to have perfect edge finish plus cover most of trunk and inside door jamb but after all that still can't do the engine bay. So $5K for factory matt finish is pretty reasonable IMO.
