I just pried out 6 plugs that were on the inside body panel of this 81 van. Two of them were full of water. Why, is this done. I know I've done this before and I think it's been on other Mopars. I mean this is an open invitation for rusted rocker panels. I've always wondered why; someone who knows tell me please. I assuming it's ok to leave them unplugged, and to clean them out, if they get clogged with debris
