Can chemicals in spray paint stay in your body for years and still travel to your brain causing clotting and damage to your brain?

I have never heard of that. On the spray can, there should be a website or a 1-800 # that you can call. I would call them or e-mail them and see what they say. Good luck. Lead has been taken out of paint for years, but, there are fumes and anything you work with that has a strong odor you should wear one of those white masks just to protect your lungs. There is no statistical reports on the effects of chemicals in spray paint harming your body. Next time, when you use something with a strong odor put on that face mask (white ones bought in any hardware store.)
