....this is probably a silly question, but today as I was scraping several sq. ft. of thick Mopar undercoating off of my projects floorpans, I was cussing the numerous plug holes. Then it struck me, what are all these holes for? Many times, for one reason or another, I've found myself scraping, sanding, painting, etc. around these holes of various sizes. Just wondering if they truly have a purpose, because if it's to prevent water problems, rust, etc. IMHO they don't work. All info appreciated.
