The last three heavy downpours, my car has developed a wet carpet on the passenger side. I plan on having a body shop diagnose the leak after Labor Day. The body guy thought it might be a clogged drain from the sunroof. The forecast is for heavy rains the next couple of days. I don't have a garage, so that is not an option. I am reluctant to put tape around the sunroof for fear of damaging the paint. Any suggestions? I have a car cover, a breathable one, and I will put some kind of plastic tarp on top--but how to hold the plastic in place? any suggestions would be appreciated
