I have a 1983 300CD which I typically don't drive when it is wet out. However, over the weekend, I was on a long drive with rain and wet roads. The floor on both sides in the front near the wheel wells got wet. I have cleaned what I thought were the drains by the hood hinges, two on each side. Is there something else that I can do.

The car does not have any rust at this time and I want to keep it that way, also I don't like to get the carpet wet on the interior. Any suggestions would be greatly appreciated. Thanks,
