Scotty, I have a 2006 Ford Escape with 85,000 miles. The exhaust pipe detatched from the muffler after crossing the train tracks on my way to school. The bottom of the car is so rusty, when I tried bolting the exhaust pipe back onto the muffler, rust flakes were sprinkling all over my face, and getting in my eyes, despite wearing a huge motorcycle helmet! Should I keep going, trying to get it back together, or should I just bring it to a muffler shop? The rust is hurting my face!
