My stangs been siting in the rain (its been raing alot in TX) and I went outside to my car and theres water siting in the floor board on the driver and pass side. Iv only managed to drive my car for about a week since I got it 6 months ago and never really got inside of it after it rained.Im gonna re weather strip the car.Iv read that the cowl vents on the car just hold water and often need to be replaced.If thats the problem then how does the cowl cover come off? Do you have to cut out the old one and weld in a new one?And could I just cut out the rusted stuff and put in one of those panels that route the water off the car instead of letting it sit?Any suggestions?
