On 1500 scratches the microfinishing will cut faster.I use Finesse it compound with a fine wool pad,then run over it again with a foam pad to remove the wool pad's swirl marks and catch any scratches not quite gone and then use Finesse glaze (or polish?) on another foam pad.Remember no wax for at least 30 days.Just keep it clean and I use something like McGuire's (sp) Instant Detailer.
