BHR, if you want to guage how bad your scratches are, see if you can feel the scratch with your fingernail...If you can, it's still probably not a disaster, but you have deeper scratches....since you didn't post any pics, it's hard to tell....most likely you have swirls etc....no big deal but you'll need a good detailer with either an orbital polisher, or rotary polisher to fix it for you.....You'll need a good one, or they'll make it worse (you're safest bet is to find one that uses the Orbital polisher, only because it's harder to screw up with an OP...if they don't know the difference or what you're talking about...red flag...find someone else.)
NXT is a great wax (I think it's better for metalics), and it has fillers, which hide (not fix) very minor swirls...You probably need to adjust your expectation of the product...More importantly though, how did you get the sratches in the first place...here's some before and after pics using an orbital polisher (pics c/o
