This is a good topic. About a week ago a model glue tube blew up in my eye, it really burned, now, I wear safty goggles when building my models. I have never used a respirator when I paint yet, I will start using saftey equipment when I start on the '50 Chevy. I have not done anything too harmful yet other than, sanding and spraying my dirt bike tank in the back of my shed. I need to take more safty precaucions than I have in the past, a start would be a respirator when painting, priming, sanding or bondoing.
