The worst episode I had with oil-based spray paint was a can of a new type of rustoleum metal red. It initially after a day or two dried to where dust would not stick and embed, but it took months for it to harden and cure/dry completely. Couldn't hardly touch the thing, and it only did harden when I put it out in the hot 95 degree sun every day for a week or two. Good looking strong paint after that. I also found it curious, that shortly after I bought it, they stopped making the paint. That drying issue I wonder, may have been the reason why they stopped selling it, but I don't know. Don't usually have such a problem with rustoleum, even in winter.
