So i just UC my 2012 black altima. Washed and clayed it first. I used DA polisher with orange pad on speed 6, did the side to side up n down pattern 6 times for each 2x2 section i taped. By the end alot of foam debris were left so i used quik detailer to remove... while i was doing this i noticed that the front and back and side skirts were darker than the rest of car!! what the heck!!!!
Got so irritated about what saw so i didnt polish or wax it... did only a lil piece with polish and wax to see if it would help but nothing....
If this makes a difference front and back bumper have been replaced due to accidents.
