Are u breaking out with a rash or just the fumes are causing you symptoms ? If it’s fumes there is nothing you can do other then avoid fumes and vapors . It’ll take time for that to go away keep car well ventilated. If your breaking out with a rash then you are having contact dermatitis and may need to see someone for patch testing to figure out what material ur reacting to . But even if it’s found out nothing you can do other then avoid contact with the material. There is no “cure” for contact derm other then don’t touch it
