New to this, but I had a quick question... We've been updating our house (built in 1964) which has cast iron baseboards and radiators throughout, and whenever we tackle a new room, we've been painting the cast iron as we go along. I've been starting to notice this season especially a nauseating smell whenever the radiators reach a certain temperature. We used Rustoleum primer (which I noticed a few of you used as well) and then a latex topcoat per room decor. I was starting to worry that maybe the Rustoleum isn't graded for such high temps and that we might be inadvertently poisoning our in-home air quality. Should I be concerned? Or is it just a characteristic of cast iron to put off an odor if there's any paint whatsoever (or dust, etc). We have a 3 yr old, so I'm especially worried about his exposure. Any input would be helpful. Thanks!
