Found another cool new surprise! This is looking down at the back of my rear wheel well behind the rock/mud guard. As you can see there is a 5mm gap between where the wheel well and quarter pannel metal meet. Im surprised this isnt already rusted out. The gap is full of dirt and crap. How bad is this considering its winter? Should i park the car till it's fixed? Is there any coating on the inside of these panels? Thanks.
