* Question for you Suburban guy's ** Am about ready to install the rear valence to bumper seal & would like to know if the seal requires any kind of adhesive . My valence is the orig. to the Suburban and is in as new condition without as much as a little nick in it. When removed for paint I don't recall if the old seal appeared to ever had any sealant on it. Was removed about 18 months ago. Your thoughts /answers will be greatly appreciated.
