It does work as an initial manual seasoning, and there are those who swear by it. Whether you want to try it depends on your opinion(s) re: dimethyl silicone (the anti-foaming agent), palm oil (perhaps of environmental concern; also coincidentally found in Crisco these days), or even soy lecithin (who knows why?). Some report using alternative brand cooking oil sprays (like Walmart Great Value, soy based, think Lodge Logic, no dimethyl silicone) which don't contain the (potentially) offensive ingredients as being a good choice. Or just use canola oil, which is essentially PAM without the extra baggage.
