You're welcome. I'd say yes to the spoiler. I think they look much better with. As for the drop, I'm not someone who thinks it needs to be done. Heck, I'm paranoid enough going over some of the potholes and speedbumps around here.
I use Meguiar's Mirror Glaze #9 Swirl Remover to clean the paint and get out small swirls. I prefer to use 3M swirl remover, because I think it's better, but I can't find it anywhere around here
I've used a few different kinds of synthetic waxes. Meguiar's Tech Wax is good. I also like Ice, but having a dark blue cars seems to show streaks from that. So I used a lot of detailer to get it off. I just tried Dupont Ion. That works nice as well. It's a lot like Ice, but not as greasy looking.
Detailers... Meguiar's, Mother's, Ice. Anything that is good. Most are ok for detailing.
