the bumper on my volvo has always had a BIG chip on the driver's side corner of the front bumper. it's flipping huge, it must have begun with a somewhat minor chip that then flaked off until it was a circle probably 3 or 4 inches in diameter. ALL of the paint is gone, and the bumper looks like the low grey side panel things below the doors.

i was wondering if there is some special technique for applying paint other than getting the special additive for touch up paint. does the bumper even require a primer? thanks in advance.

oh yeah, is there supposed to be grey trim on the front bumper, like there is on the rear and low sides? cause mine doesnt have any...
