Sherwin Williams Emerald Still "Soft"???
We are painting the aluminum siding on our home. It has never been repainted and is likely 30-40 years old. There are some spots where someone dripped paint (from window trim, and painting a chimney). These spots are rock hard and I can't scrape them off. However, even though we scrubbed the siding before painting, the portion we've painted with "Emerald" (supposedly even better than "duration") and the sample we got to be sure we liked the color in "Resiliance" can easily be scraped off with a fingernail. The "Resiliance" seems softer but not much-this one was painted over a MONTH ago! Both portions are inside of a covered sunroom with no exposure to rain, and it certainly warms up inside. Has anyone used either of these and if so, did it ever actually cure to a reasonably hard coating? I'm afraid to keep going with it, yet I cant' really afford to toss several gallons of paint. The point was to make the place look BETTER, not coat it with paint that's not going to stick and harden!
