WARNING: This page is about a different car, the 2008 Acura TL and 2007 Acura TL. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: To make an effective repair, the broken section must be no longer than 1 inch (2.5 mm).

Lightly rub the area around the broken section (A) with fine steel wool, then clean it with isopropyl alcohol.
