the lady I bought my mustang from had a car bra on the front, wich was first thing I took off when I got home... .... however the whole front bumper is full of nasty rock chips/paint chips... and a bubble.. rite where the licence plate would go there is a buble, its noticeable, the bumper seems to have warped or something... any idea how I fix that... can I sand it down like the rest of the bumper and just use color match spray paint from the local store and clean it up until I can eventually afford a wrap for the car or new paint job... I just ordered smoke headlights, mach 1 grill delete and chin spoiler and need to fix this bumper up asap before the install
