Had a 6x12" spot on the hood of my wife's huyundai.
Not sure what it was but looked like it might buff out.
Got some polish/cut compound and DA out while wife was getting ready to wash the car.
Did the hood and driver's door, wiped off the compound and looked like the spot came out.
Went in the shop to get a better rag and when I came out the wife was buffing the other side of the car.
Never done it before, just 15 min of watching me do it.
L O V E that woman!
...and yes, she could check her makeup (what little she wears) in the paint afterwards.
