Twin Turbo '74 Duster

I guess if you park your car outside I could see how that could happen quite bad. I think painting with VHT High Heat paint and then wrapping them after break in would help the issue. A garaged vehicle would have less issues than one that is not.
Hate to rehash this but........if you live in a climate with temp./humidity swings parking in a garage will not do you much good. Live in Eastern Washington. Parked my truck in the garage for some maintenance. It sat for a few days before I got to it and the motor/exhaust manifolds were covered with moisture. So being garaged is not really going to be of much help.....at least up my way.......
