The original post stated he wanted something good for his health. With that said, all the post are correct and the new formulas don't work well. In fact you'll putting on multiple coats which in turn raise the risk. My suggestion is if you have access to an air compressor, get a DA and sand the finish off. It's safer than stripper and now a days will be faster and more effective. Plus you won't run the risk of having contamination in the new paint. And truthfully, with stripper you need to wash it off, so now you're putting water on bare metal and you're gonna get flash rust which will need sanded. JMO
