So with recent snow and salt on michigan roads, i have noticed bubbling paint on the bottom/corner edge of my drivers door. Very minor and is not noticable from a distance but up close it's ugly lol. I do wash my car about every two weeks to keep road grime and salt off the body but some days the weather doesn't allow for it. I also have a small dime sized spot of bubbling paint on the rear driver's side quarter panel where the bumper cover mates to the body. Given the car is 14 years old and was originally from ohio the car is about 98% rust free. Rust is inevitable on any car in the mitten state. Any suggestions on how to keep the oxidation at bay?? Atm i don't have any pics to upload but any help would be appreciated!
